A flight sim PC built for the way you actually fly.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
