I'm building my first PC in the UK and would appreciate a second opinion before spending around £3,500, which is about £500 over my original budget. The system is mainly for gaming, but I'd also like to experiment with local AI/ML workloads and possibly expand it for 24/7 server hosting later.
The current parts are a Ryzen 9 9950X3D, Noctua NH-D15S, Gigabyte Gaming OC RTX 5080, Gigabyte X870E Aorus Elite WiFi 7 motherboard, 64GB of DDR5-6000 CL30 memory, a 2TB WD NVMe SSD, Antec P20CE case, and a 1000W Corsair RM1000x power supply. I plan to run Fedora Linux.
The 64GB memory kit costs about £875 by itself, so I'm especially interested in whether there are more affordable alternatives. I'm open to changing any component if there are better-value options, and I'd also like advice on compatibility, cooling, airflow, upgrade potential, and whether this platform makes sense for gaming alongside AI work and future server use.

For local AI, GPU VRAM is often more important than system RAM. Depending on the models you want to run, a used RTX 4090 with 24GB of VRAM could be more useful than pairing 64GB of system memory with a 16GB or 16GB-class graphics card. It is worth researching your specific models before buying.
I’d also avoid planning to run a serious 24/7 server from your main gaming PC. A separate used enterprise or DDR4-based machine can be cheaper, easier to maintain, and avoids leaving your expensive gaming system running continuously. If server workloads and heavy AI are definite priorities, a workstation platform such as Threadripper may offer more expansion and PCIe bandwidth, though it is less efficient for this gaming-focused budget.
For gaming alone, this is more than you need. A Ryzen 7 9800X3D with 32GB of memory would likely feel almost identical in games and save a substantial amount. Since you’re also considering AI/ML, keeping the 9950X3D and 64GB is more understandable. Unfortunately, high-capacity DDR5 kits are unusually expensive right now, so the memory price may simply reflect the current market rather than a bad choice.
The biggest easy savings are outside the CPU and GPU. A Thermalright Phantom Spirit should cool this chip very well for roughly a third of the Noctua’s price. You probably don’t need an expensive X870E board either; a quality B850 model should provide everything you need unless you have a specific requirement for extra connectivity or expansion lanes.
For gaming, an RTX 5070 Ti is worth considering. It is only around 12–13% slower in many workloads, still has 16GB of VRAM, and could save more than £250. A better-ventilated case with a few additional fans would also be a worthwhile improvement. A 1000W supply is excessive for the 5070 Ti, but keeping a high-quality unit gives you useful upgrade headroom. These changes could bring the system close to £3,000 without sacrificing much practical performance.
The 9950X3D makes sense if you’ll actually use its extra cores, but it’s worth checking whether your workloads benefit from it. For gaming, especially at 4K, a regular high-end Ryzen 9 may perform similarly. Also, 6000 MT/s CL36 memory is usually cheaper than CL30 and makes very little practical difference. If you keep the X3D chip, make sure the appropriate cache-priority settings are enabled in the firmware.
That’s useful to know. I’m hoping the extra cores will help with shader compilation, development tools, and occasional CPU-heavy workloads, so I may keep the 9950X3D if the rest of the build can be trimmed.
