I'm in the United States and want to build a very cost-effective gaming PC, preferably for less than $3,000. I don't need peripherals, and I'd rather prioritize raw performance, compatibility, and value over premium features. I use Linux, so I don't need extra memory for Windows, but I'm considering 16GB of DDR5 with around CL30–34 timings. I'd like 1–2TB of PCIe Gen 4 NVMe storage and a reliable AIO CPU cooler. The system should be reasonably future-proof and handle my games at 1440p on high to maximum settings, ideally around 144–240 FPS where possible, with some VR capability. My games include Bloons TD 6, Counter-Strike 2, Cyberpunk 2077, Elden Ring and Nightreign, Garry's Mod, Kerbal Space Program, Minecraft with heavy mods and shaders, No Man's Sky, PEAK, Portal, Raft, Roblox, R.E.P.O., Satisfactory, Subnautica, Subnautica 2, Subnautica: Below Zero, Terraria, and Trailmakers. I currently use Nobara Linux, and nearly all of these games work well for me aside from Subnautica 2, which is still in early access and receiving compatibility updates.

It’s worth checking a current parts list rather than spending the entire budget automatically. A well-balanced build can likely meet your goals for considerably less than $3,000, especially if you avoid unnecessary premium parts. Also, verify Linux support for any games that use anti-cheat or are still in early access, since compatibility can change independently of the hardware.
A strong value-oriented build could use a Ryzen 7 7800X3D or 9800X3D, 32GB of DDR5, a suitable B850 motherboard, a 2TB PCIe 4.0 NVMe SSD, and a Radeon RX 9070 XT. Add a good 850W power supply and choose the case and cooler based on your preferences. For an X3D processor, exact memory latency is less important than getting a stable, reasonably priced kit. Radeon is also a sensible choice for Linux because of its generally strong open-source driver support.
I’m about an hour to an hour and a half from a Micro Center, so I’ll definitely look into their CPU, motherboard, and memory bundles. Are their bundle prices usually significantly better?

That makes sense. My current Nobara system runs the listed games well apart from Subnautica 2, so I’m mainly trying to improve performance and gain more headroom for newer games and VR.
