Best workbench specs for PLAXIS3d

This should hopefully be a pretty self explanatory post. What would be the best desktop setup to run PLAXIS 3D as fast as possible without being wasteful?

Currently I'm thinking:

AMD Ryzen 9 7900X 12 Cores (my understanding is PLAXIS 3D can't really make use of more than 8 cores, is this correct?)

Corasir RAM 2 x 16 gb 6000mhz CL30 (is there any benefit to faster RAM?)

For storage I was going to go with a 1tb or 2 tb NVMe SSD. Is there any benefit to going with PCIe Gen 5 over a cheaper Gen 4?
