I'm planning my first gaming PC with a dedicated graphics card in many years, targeting 1440p gaming at 60 FPS or higher on high or ultra settings. I mainly play open-world games such as Cyberpunk, GTA, and Far Cry, along with competitive FPS titles. Linux will be my primary operating system, although I'll dual-boot Windows for games that require anti-cheat software.
The current build includes a Ryzen 9 9900X3D, Thermalright Peerless Assassin 120 SE, an MSI B850 motherboard, 32GB of DDR5-6000 memory, a 2TB PCIe 4.0 NVMe SSD, an RTX 5070 Ti, a Fractal Design North case, and an 850W power supply. The listed total is about £2,526 in the UK, though I may delay buying the graphics card until prices improve.
My main concern is whether the Peerless Assassin 120 SE is sufficient for the 9900X3D, or whether I should use an AIO cooler instead. I'd also appreciate feedback on the processor, graphics card, Linux compatibility, storage, memory, and any other parts that could be improved. Since I may keep the GPU for around five years, I'm particularly interested in the best long-term choice for 1440p gaming.

For a gaming-focused system, I’d choose the Ryzen 7 9800X3D over the 9900X3D. The 9900X3D uses two six-core chiplets, and only one has the extra 3D cache, so game performance can be worse than the 9800X3D despite the higher core count. The 9800X3D keeps all eight cores on one chiplet and is generally the better gaming CPU. The Peerless Assassin 120 SE should handle either processor without a problem; an AIO isn’t necessary unless you specifically want one. The newer Phantom Spirit is another good air-cooling option.
Nvidia cards can work on Linux, but their proprietary driver stack can still involve more troubleshooting than AMD’s generally better-integrated open drivers. Your Linux experience should make it manageable, but AMD is usually the smoother choice for a Linux-first machine.
A few other changes could improve the value of the build. The 9800X3D is typically faster for gaming than the 9900X3D, and you can use a 32GB DDR5-6000 kit with slightly better timings for less money. A similarly rated 2TB SSD may also cost considerably less without noticeable gaming differences.
The RTX 5070 Ti looks particularly expensive at the listed price, and AMD may offer better Linux compatibility and performance for this use case. The Fractal case and Corsair power supply are good products, but both may carry a premium compared with alternatives of similar quality. Also double-check the unusually high prices shown for the memory and SSD, since they may be pricing or listing errors.
I’m still considering the 5070 Ti because I might keep the card for five years. Would the lower core and thread count of the 9800X3D create problems in future CPU-heavy games, such as a later GTA release, or is the gaming performance advantage more important?
Is Nvidia support still a major problem today? I’ve seen that official drivers are available, and I work with Linux professionally, so I’m comfortable troubleshooting if necessary. I’m mainly wondering whether the setup is merely less convenient or genuinely troublesome for gaming.
