Upgrade your CPU to an i9 7900X for enhanced performance.
Upgrade your CPU to an i9 7900X for enhanced performance.
There doesn’t seem to be a clear upgrade route from your i9 7900x to the 3090 FE. The performance gap might come from differences in CPU speed and architecture, even though you have a solid PSU and RAM. Your current setup is strong, but the newer 3090 FE could offer better efficiency or features that aren’t immediately visible online.
The system offers numerous cores for gaming setups, but the only real upgrade would be the 9th generation HEDT, which shares the same architecture. This might allow better overclocking with a 9900X, though the gains would be minimal. These chips aren't readily available at good prices. For more flexibility, consider disabling two cores to attempt higher overclocks. If you aim to enhance CPU performance, investing in a new motherboard and CPU is the best approach.
The HEDT platform seldom delivers optimal outcomes for gaming. For dedicated gaming, popular choices perform better. While top-tier CPUs exist, they probably won’t significantly boost your frame rate. Still, could the extra 30 frames from a CPU upgrade matter in your situation? With a 3090, you’re already getting solid performance. It’s unlikely a swap will noticeably change your experience. The impact depends on your needs—are you comparing 300 to 350 FPS or running AAA titles at full resolution? Higher average FPS makes changes less obvious.

If you're still looking, the upgrade guide for this processor is available here: https://www.cpu-upgrade.com/CPUs/Intel/C...7940X.html. I own two machines running this chip, and both performed well for my tasks. However, I mostly depended on GPUs, which sometimes gave me better results than the E5 2690 v3. Now, newer Xeon models like i9 9940X through i9 12900K are popular options, but neither fits upgrading the i9-9940X.
