I doubt memory makes a major difference above 32gb. I have 64gb (I’ll likely be selling 32gb of it as it’s expensive) and I have had no real returns on that excessive amount of RAM.
I have a 5820k CPU and I’m starting to feel it doesn’t quite cut it for LightMass if I am going for very high quality. I’m thinking of upgrading to a 8700k. My question is, is speed more important, or core/thread count? Because the 8700k is still 6 cores, whereas I could get Skylake-X or some other ridiculous thing for more cores/threads if that mattered more?
