I put in a minimum of 32GB RAM, 16 GB Dedicated to ROMEX PrimoCache 2 Level cache, 16 for the system. The Big Platters store TBs of everything, the commonly & frequently used apps, games, programs, and data cache to an SSD, and the things I am currently using are running at RAM Drive speeds off the level 1 RAM Cache. Even the largest programs run at RAM Drive speeds. You could do near the same results with 16 GB. 8 system / 8 cache - if you like.
