Thanks again for your help. Please tell me, the i9-12900k system is cheaper due to DDR4 and cheaper boards, but as I understand it, it loses to the 7900X (and 7950X) due to the fact that it actually has only 8 productive cores, right? Does it make sense to save a few hundred dollars and build on the i9-12900K, or is it better to build on the 7900X (or 7700X)? And what kind of motherboard do you have for 7950X, if it's not a secret 🙂 And how do you cool the 7950X3D? Do you have an air or liquid cooling system? Thanks again for your help, you help me a lot! 🙂
