> For memory bound operations, memory performance dominates.

I kept this in mind for my build and went with DDR4-3600 RAM as well as an M.2-2280 NVME SSD 😁. I also got inspired to start [a thread for showing off Julia performance on PCs that people build/have](https://discourse.julialang.org/t/show-off-julia-performance-on-your-pc/33606) so check it out! Thanks so much for your response!!
