Does it make sense to use 4x32Gb RAM or 2x64Gb is the only reasonable option?

Hi, I currently own: GPU: RTX5080 CPU: AMD 9950 x3d RAM: 2x32Gb DDR5 6000MT/s 30CL Aaaaand I'd like to slowly gear up to be able to run bigger models OR run them faster. Obviously GPU is an important factor here (and I'm planning to change it to RTX5090), but the immediate and cheaper upgrade is to increase my RAM. I could buy 2x64Gb instead of my current 2x32Gb (but with worse stats, 2x64Gb are hard to get now and almost nonexistant with 6000MT/s. I found some available with 5600MT/s and 40CL though). But changing my RAM to 2x64Gb, while probably better, is also much expensive.
