Microsoft Flight Simulator 2024 is one of the most demanding consumer applications you can run on a PC. Microsoft's own "ideal spec" calls for 64GB of RAM — most games don't even use half that.

If you've been shopping prebuilt gaming PCs and not finding anything that's actually configured for flight sim, that's not your imagination. The big-box prebuilts are tuned for esports framerates, not for the workload flight sim creates. We offer custom builds spec'd specifically for serious flight simulation — and we'll walk you through every component choice before we order anything.

Who this custom build is for

This page is about a build aimed at 4K-capable, high-refresh, no-compromise flight simulation in New Jersey. If you want a budget-tier rig for casual flying, we can spec that too — but this page focuses on the high end.

MSFS 2024 / 2020

Photogrammetry on, live weather streaming, payware aircraft (PMDG, Fenix), AI traffic, charts on a second display.

🛩

X-Plane 12 + payware

Heavy scenery, study-level aircraft, real weather and traffic without frame collapse on final approach.

🎯

DCS World & VR

Full-fidelity modules, multiplayer servers, Quest 3 or Pimax Crystal headsets at high settings with headroom.

Why each component matters for flight sim

This is where most flight sim PC pages fall short — they list parts without explaining why. Here's what each major component does for flight simulator specifically, and why we recommend what we do.

🧠
Processor

Ryzen 7 9800X3D

Flight sim is heavily CPU-bound. MSFS 2024 streams photogrammetry tiles, traffic data, and weather in real time while the CPU calculates physics, ATC behavior, and aircraft systems. Single-thread speed and cache size matter more than raw core count.

Why X3D specifically: The 9800X3D has 96MB of L3 cache thanks to AMD's 3D V-Cache. In flight sim benchmarks, X3D chips dramatically outperform non-X3D processors at the same price — sometimes by 25-40% in CPU-bound scenarios like dense city flyovers. Hardware Unboxed benchmarks confirm the 9800X3D runs 26-35% faster than Intel's Core Ultra 9 285K in gaming — even when Intel is paired with faster DDR5-8200 memory. For pure flight sim, it's the clear choice.
If you also stream or record flights: The Ryzen 9 9950X3D adds 8 more cores (16 total) on top of the V-Cache design. OBS Studio, 4K recording software, and livery tools running alongside MSFS 2024 can saturate the 9800X3D's 8 cores. The 9950X3D handles the sim on its cache-heavy cores while offloading background work to the rest — no compromise needed. Hardware Unboxed testing shows the 9950X3D narrows the gaming gap to single-digit margins in heavily threaded workloads. Tell us your full workflow at the consultation and we'll spec the right chip.
🎮
Graphics Card

RTX 5080 or 5090 (16-32GB VRAM)

The GPU paints the world — cockpit, terrain, weather, clouds, aircraft liveries. At 4K with high settings, the demand on VRAM is significant. Tom's Hardware tested 23 GPUs in MSFS 2024 and confirmed that at 4K Ultra, 8GB cards run out of VRAM and produce what they called "a choppy mess." At 4K ultra, even reaching 30 FPS proves challenging without a card in the $500+ tier — and that's before payware aircraft and heavy add-ons enter the equation.

Why high VRAM matters: Payware aircraft with 4K liveries, photogrammetry, and busy ramps at major airports can consume 16-20GB+ of VRAM. The 5090's 32GB future-proofs you against scenery and aircraft add-ons that haven't released yet.
RTX 5080 vs 5090 — the honest breakdown: If you're targeting 4K at 60fps (not 240Hz), flying MSFS 2024 without a VR headset, and not running the heaviest payware simultaneously, the RTX 5080's 16GB frequently hits that target with money left over for peripherals. The 5090's 32GB earns its cost when you're running VR (rendering the scene twice), stacking 4K payware liveries with photogrammetry maxed out, or want genuine headroom for add-ons releasing over the next 2-3 years. We'll walk you through the tradeoff at the consultation — there's no upsell here, just matching the build to what you actually fly.
📦
Memory

64GB DDR5-6000

Microsoft lists 64GB as the "ideal spec" for MSFS 2024 — almost unheard of for a game. The reason: photogrammetry and world data get held in system memory while the GPU works.

Independent verification: PC Gamer tested MSFS 2024 with up to 96GB of RAM and found that with 16 or 32GB, the sim "badly jerks and lags as it tries to load in the world when starting a flight." With 64GB, it's "almost stutter-free." Microsoft itself lists 64GB as the ideal spec — not recommended, ideal.
💾
Storage

1TB + 4TB Gen4 NVMe (dual drive)

The sim constantly pulls scenery tiles off disk during flight. Slow storage means stutter on approach as the system waits for new tiles to load. Gen4 NVMe is the floor for serious sim use.

Why two drives: Windows and core programs go on the 1TB so they don't fight for I/O with scenery. The 4TB is dedicated scenery storage — payware airports alone can be 20-50GB each, and add-on regions add up fast. Running out of space mid-collection is a real problem.
Cooling

360mm AIO + high-airflow case

Flight sessions are long — 2 to 6 hours isn't unusual. Your CPU and GPU need to hold boost clocks the entire flight, not throttle after 30 minutes. Sustained thermal performance is different from burst performance.

What this prevents: Thermal throttling mid-flight, which presents as gradual frame rate decay over a long leg, fans ramping aggressively, and components running near their limits. Proper cooling means the rig sounds the same at hour four as it did at takeoff.
Power Supply

1200W 80+ Gold

A serious flight sim setup has a lot of USB devices plugged in: yoke, throttle quadrant, pedals, multi-panel, radio panel, switch panel, headset, monitors. PSU sizing isn't just about the GPU — it's about everything drawing power simultaneously.

Why we don't undersize: An undersized PSU causes random USB disconnects mid-flight (yoke loses input, throttle stops responding), unexpected shutdowns under load, and zero headroom for future GPU upgrades. We'd rather build it once and right.

Why a "gaming PC" isn't the same as a flight simulator PC

The number one reason people end up unhappy with a prebuilt gaming PC for flight sim is that those builds are tuned for the wrong workload. A high-refresh esports build and a flight sim build use similar parts — but the priorities are different.

1
Cache matters more than clock speed MSFS 2024 and X-Plane 12 stream a lot of data through the CPU. The X3D chips with stacked L3 cache outperform faster non-X3D chips in flight sim because more of the working data stays close to the cores. A "faster" CPU on paper can lose to a slower X3D chip in this specific use case.
2
64GB of RAM, not 16 or 32 Microsoft's official ideal spec is 64GB. Independent testing confirms it's not just marketing — the difference between 32GB and 64GB is the difference between stutter and smooth on flight loading and traffic-heavy scenarios. Almost no other game cares this much about system memory.
3
VRAM headroom for photogrammetry and payware 4K photogrammetry plus a study-level payware aircraft plus a busy ramp will exhaust 8-12GB cards. 16GB is the practical minimum for 4K, and 32GB future-proofs you against the increasingly heavy scenery and aircraft add-ons coming out.
4
USB bandwidth for peripherals A serious cockpit can have 10+ USB devices plugged in. The motherboard needs enough native USB lanes — not just a USB hub stuffed full — to keep input latency low and prevent the random disconnects that ruin a long flight. We pick motherboards with this in mind.
5
NVMe throughput, not just capacity Cheaper SSDs have lower sustained write speeds and can stall under continuous I/O. Flight sim is one of the few games that hits storage continuously throughout a flight. Gen4 NVMe is the right tier; we put scenery on its own dedicated drive so it isn't competing with Windows.

Why NJ airports are the real benchmark for your build

Most flight sim PC guides benchmark with generic scenery. If you're flying out of New Jersey, your real-world test is harder than anything those benchmarks show.

KJFK, KEWR, KTEB, and KPHL are all fully photogrammetric in MSFS 2024 — and they sit in one of the most congested airspace corridors in the sim. Approaching KEWR from the west with live weather injected, AI traffic on, and a study-level payware aircraft loaded is one of the most CPU- and VRAM-intensive scenarios the sim produces. We've seen machines that score fine in benchmark videos fall apart on approach to Newark.

When we talk through your build, we'll ask where you fly most. That answer changes the spec conversation — a sim pilot who does bush flying in Alaska has different bottlenecks than someone flying ILS approaches into JFK in IMC. We build for your routes, not a generic benchmark.

KJFK / KEWR photogrammetry load Both airports are fully rendered from aerial survey data. Dense terminal geometry, taxiway lighting, and AI traffic at gate means the GPU and CPU are at or near maximum simultaneously on approach. This is where 8GB VRAM cards fail first, and where a weak CPU bottlenecks a strong GPU.
KTEB VFR pattern in live weather Teterboro sits directly under the Class B shelf with real GA traffic. Running live weather and ATC simultaneously pushes the sim's networking and CPU threads hard. The 9800X3D's large L3 cache is what keeps this from dropping frames on the downwind leg.
KPHL — the Fenix A320 on short final A study-level aircraft like the Fenix A320 or PMDG 737 adds thousands of simulated systems running on top of the world simulation. Flying a payware airliner into Philadelphia International at dusk with rain is the combination that separates properly-specced flight sim hardware from "gaming PCs."

Three builds, three flying profiles

Not every flight sim pilot needs the same machine. Here's how we think about the three main build profiles we spec — based on how you actually fly, not a single "best" configuration.

🎯
Profile A

The 4K/60 Sweet Spot

Who it's for: Serious sim pilots flying study-level payware aircraft on a single 4K monitor with no VR, no streaming. MSFS 2024, X-Plane 12, or DCS without the highest-end VRAM demands.

CPU: Ryzen 7 9800X3D  ·  GPU: RTX 5080 16GB  ·  RAM: 64GB DDR5-6000  ·  Storage: 1TB + 2TB Gen4 NVMe
Target: 4K Ultra, 50-65fps on MSFS 2024 — smooth approach into KEWR with live weather and a Fenix A320 loaded.
Profile B

The No-Compromise Build

Who it's for: Pilots who want the sim maxed out — VR headset support, heavy payware, 4K at high refresh, and room to grow for 2-3 years of new add-on releases.

CPU: Ryzen 7 9800X3D  ·  GPU: RTX 5090 32GB  ·  RAM: 64GB DDR5-6000  ·  Storage: 1TB + 4TB Gen4 NVMe
Target: 4K/high-refresh, Quest 3 or Pimax Crystal VR, photogrammetry fully on, payware liveries at max resolution.
📹
Profile C

The Streaming Cockpit

Who it's for: Sim pilots who stream to YouTube or Twitch, record 4K flight videos, run heavy background tools (OBS, replay software, live ATC tools), or use the PC for video editing between flights.

CPU: Ryzen 9 9950X3D  ·  GPU: RTX 5090 32GB  ·  RAM: 128GB DDR5-6000  ·  Storage: 1TB + 4TB + dedicated recording drive
Target: Simultaneous 4K sim + OBS encoding with no frame budget going to the background tasks. The 9950X3D's extra cores absorb the overhead that would otherwise tax the 9800X3D.

These are starting points — we'll adjust storage, RAM, and GPU based on current part availability and your actual budget. Call or stop in and we'll put together a written quote the same day.

Custom flight sim PC builds across New Jersey

We're at 75 N Bridge St in Somerville — central New Jersey, easy to reach from most of the state. Customers drop in from across Somerset, Hunterdon, Middlesex, and Mercer counties for custom builds, and from further out for specialized work like flight sim and workstation rigs.

NJ areas we regularly serve for custom builds:

Somerville
Bridgewater
Hillsborough
Bound Brook
Flemington
Edison
New Brunswick
Princeton
Warren
Montgomery
Bernardsville
Basking Ridge
Bedminster
Branchburg
Raritan
Manville

One thing to know up front: we're walk-in / drop-off only at the Somerville shop. We don't offer in-home or on-site PC building or setup anywhere in NJ — every build happens at our bench. Curbside pickup is fine when your build is ready; call when you pull up.

Pricing

We don't publish fixed prices on custom builds anymore — and we want to be honest about why. GPU and high-capacity memory pricing is moving every week right now because of AI demand, supply constraints, and tariff changes. A number we posted last month is wrong this month.

Posting an inflated "safe" number is worse — it makes us look expensive when reality is often better. Instead: call 908-428-9558 or stop in. We'll spec your exact config, price it against this week's actual part costs, and put it in writing. The consultation is free; no obligation until you approve the build.

New customer discount: DAVESXP25 — $25 off labor on your first custom build. Mention at drop-off. One per household.

Frequently asked questions

These are the questions we hear most often, plus the questions most commonly searched on Google about flight simulator PC builds.

What PC do I need for Microsoft Flight Simulator 2024?

Microsoft's official "ideal spec" for MSFS 2024 calls for a Ryzen 9 7900X or Intel Core i7-14700K, 64GB of RAM, an RTX 4080 or RX 7900 XT with at least 12GB of VRAM, and a 100Mbps internet connection.

For a current-generation 4K build with payware aircraft, we'd push that further — a Ryzen 7 9800X3D, 64GB DDR5, and an RTX 5080 or 5090 with 16-32GB of VRAM. The X3D chip's large L3 cache delivers substantially better performance in flight sim than non-X3D processors at similar price points.

Is 32GB of RAM enough for MSFS 2024?

Not for a smooth experience. PC Gamer ran a dedicated RAM test on MSFS 2024 and found that with 16 or 32GB of RAM, the sim "badly jerks and lags as it tries to load in the world when starting a flight." With 64GB, it's "almost stutter-free." Microsoft itself calls 64GB the ideal spec — not recommended, ideal. That's unprecedented for a consumer game.

For any new flight sim build in 2026, we strongly recommend starting at 64GB. The cost difference between 32GB and 64GB DDR5 is small compared to the experience difference.

How much VRAM do I need for flight simulator at 4K?

At 4K with high settings, 8GB VRAM cards run out of memory in dense cities and busy airports — independent testing has shown this produces "a choppy mess." 12GB is the practical minimum for 4K, 16GB is comfortable, and 24-32GB gives you headroom for payware aircraft with high-resolution liveries, photogrammetry on, and VR.

For a serious 4K flight sim build today, plan for 16GB VRAM at minimum. For long-term peace of mind, 24-32GB.

Is the Ryzen 7 9800X3D better than the 9950X for flight simulator?

For flight sim specifically, yes — in most cases. MSFS 2024 is heavily cache-dependent because of how it streams world data. The 9800X3D has 96MB of L3 cache (thanks to AMD's 3D V-Cache), which dramatically reduces stutter in CPU-bound scenes like dense cities and busy approaches.

The 9950X has more cores but less effective cache for this workload. For pure flight sim performance, the 9800X3D usually wins. The 9950X3D combines high core count with 3D V-Cache and is the right pick if you also do heavy multitasking, streaming, or video editing alongside flight sim. Hardware Unboxed benchmarks show it narrows the gaming performance gap to single-digit margins in heavily multithreaded workloads.

Can I run MSFS 2024 in VR? What PC do I need?

Yes, but VR is significantly more demanding than flat-screen flight sim because the GPU is rendering the scene twice (once per eye) at high resolution and refresh rate.

For Quest 3, Pimax Crystal, or Varjo headsets at high settings, plan for an RTX 5080 or 5090 with 16-32GB of VRAM, 64GB of system RAM, and a top-tier CPU like the Ryzen 7 9800X3D. Lower-tier hardware will work but you'll be turning settings and resolution scaling down to maintain frame rates.

Do you build custom flight simulator PCs in New Jersey?

Yes. Dave's Computers in Somerville, NJ offers custom flight simulator PC builds for customers across New Jersey. We help you spec the right components for your specific use case — MSFS 2024, X-Plane 12, DCS World, VR, multi-monitor — and build the machine at our shop.

We're walk-in and drop-off only at 75 N Bridge St, Somerville NJ 08876. We don't offer in-home or on-site PC building anywhere; every build is done at our bench.

How much does a flight simulator PC cost in 2026?

A serious 4K-capable flight sim PC in 2026 falls in the high-end custom build range, but exact pricing changes weekly. GPU and high-capacity memory prices are moving constantly because of AI demand and tariff changes — a number we publish today would be wrong by next week.

Call us at 908-428-9558 or stop by the shop and we'll quote your exact build against current part prices, in writing, with no commitment. The consultation is free.

Do I need a high-end GPU or a high-end CPU for flight sim?

Both, but the CPU matters more in flight sim than in most games. MSFS 2024 and X-Plane 12 are heavily CPU-bound in dense scenarios — over big cities, near major airports, in heavy weather. A top-tier GPU paired with a weak CPU will still stutter on approach to KJFK or KEWR.

The right balance: a strong cache-heavy CPU (Ryzen X3D series), 64GB of fast DDR5 RAM, and a GPU sized to your target resolution. We'll help you pick the right balance during the build consultation rather than overspending on one component.

What's the difference between a gaming PC and a flight simulator PC?

A standard gaming PC is usually tuned for high frame rates in esports or AAA titles: fast GPU, decent CPU, 16-32GB of RAM.

A flight simulator PC is tuned differently. It prioritizes CPU cache (for streaming world data), large amounts of fast RAM (64GB minimum), high VRAM (for photogrammetry and payware aircraft), fast NVMe storage (for scenery streaming), and a high-wattage PSU (for peripherals). Same category of components, very different priorities.

Does Microsoft Flight Simulator need fast internet?

Yes. MSFS 2024 streams photogrammetry, real-world weather, and AI traffic continuously in real time. Microsoft lists 10Mbps as minimum, 50Mbps as recommended, and 100Mbps as ideal.

Slower connections result in lower-detail scenery, pop-in, and delayed weather updates. A wired Ethernet connection or strong Wi-Fi 6/6E is recommended. If you're already in an area with decent broadband (most of NJ qualifies), you're fine.

Can I bring my yoke, throttle, and pedals to be set up with the new PC?

Yes — bring them in when you drop off, or just bring a list of what you own (Honeycomb Alpha/Bravo, Logitech, Thrustmaster, Winwing, Virpil, VKB, VirtualFly, etc.).

We'll make sure the motherboard has enough USB bandwidth and the power supply has the headroom to run everything without random disconnects mid-flight. This is one of the things prebuilt PCs commonly get wrong.

What about real-world flight training — can I use this for procedure practice?

This hardware will run anything you want to throw at it — IFR procedures, holds, partial-panel work, type-specific procedure trainers. It's a strong platform for personal proficiency work.

Note: we're not a certified FAA ATD/BATD vendor (those have specific paperwork and approvals). For personal use, procedure rehearsal, and skill maintenance, the hardware is more than capable.

How long does a custom build take?

Typically 1-2 weeks from approved spec to pickup, depending on parts availability. Some components on this tier of build can have lead times — we'll give you a realistic timeline at the consultation and update you if anything shifts.

If something is faster or slower than expected, you'll hear from us — we don't leave customers wondering.

What if something goes wrong after I take it home?

Every custom build comes with a hardware warranty and post-build support. If something acts up, bring it back to the shop and we'll handle it.

We've been in business in Somerville since 2011 and have 400+ Google reviews. The post-build support is the part nobody talks about until they need it, and it's the reason a lot of our work comes from referrals. We've been at the same address in Somerville since 2011 — you can always walk back in.

Where in New Jersey is Dave's Computers located?

75 N Bridge St, Somerville, NJ 08876. Central New Jersey, easy access from Routes 22, 287, and 206.

Hours: Mon-Fri 10am-5pm, Sat 9am-2pm. Phone: 908-428-9558. We serve customers across Somerset, Hunterdon, Middlesex, Mercer, and surrounding counties. Walk-in and drop-off only — no on-site or in-home service.

Do you help with sim setup, controller bindings, and add-on questions after the build?

Yes — and this is worth asking any builder before you commit. When you pick up your build, we make sure everything is working: controllers recognized, USB devices not conflicting, sim launching clean. Bring your yoke, throttle, and pedals at drop-off and we'll verify compatibility on the bench before you take it home.

On follow-up visits we help with MSFS 2024 settings, add-on installation questions, and controller binding issues. We're a local shop you can walk back into — not a mail-order operation that ships you a box and ends its involvement at delivery.

Is the Ryzen 9 9950X3D worth it over the 9800X3D for flight sim?

For pure flight simulation, the 9800X3D is still the better value — its 96MB L3 cache handles the sim's streaming workload more efficiently than extra cores alone.

The 9950X3D makes sense when you're running significant workloads alongside the sim: streaming to YouTube or Twitch via OBS Studio, recording 4K flight video, editing liveries or video between sessions, or doing anything CPU-intensive in the background. It adds 8 more physical cores on top of the V-Cache design, which absorbs that background overhead without touching the sim's performance budget. Hardware Unboxed testing confirms the 9950X3D closes the gap in heavily threaded scenarios to single-digit margins. If your PC does more than just fly, it's worth the conversation.
