I originally planned on buying a i9-14900K, then all the Intel stuff happened, so I thought of a i9-12900k. But wouldn´t the 5090 bottleneck the CPU going down to 12th gen? Is it really that much of a bad idea to get a 14th gen, even knowing its issues? Do you recommend AMD processor with the 5090?

Btw, I´m building the PC for 3D high-end simulations, that´s why I´m interested in the 5090
