Currently, my system has 3 normal HDDs.
The first drive contains my OS and programs, the second drive contains my games and the third contains random tools and documents for long term storage (not accessed often).
Games seem to be taking a while to load but once they load they run fine.
I have a Core i5 8600k and motherboard that support Optane.
My motherboard has one empty M.2 slot.
Would I benefit more from getting a M.2 SSD or Optane to speed up the boot drive? And then I would move games that take more time to load to the main drive, keeping less intensive games in the game drive.
