Frequently Asked Questions
Will my Threadripper CPU bottleneck these GPUs?
No. At 4K resolution, the GPU is the limiting factor. The 9945WX provides more than enough processing power to keep the GPU fully saturated without any bottlenecking.
Is 12GB VRAM enough for 4K gaming in 2026?
It is sufficient for most titles at High settings, but 16GB is recommended for Ultra textures. Use DLSS or FSR upscaling to maintain performance if VRAM usage spikes.
Can I use a standard gaming motherboard with this CPU?
No, the Threadripper PRO 9945WX requires an sTR5 socket motherboard. Ensure your chassis supports E-ATX form factors, as these boards are significantly larger than standard consumer hardware.
