I have several drives, but the game resides on the same drive as windows. Actually I might have a gig of ram. I forget already :>
Ok. Normally a game like Far Cry smoothes out at a gig of RAM (that's if you like to push the graphics). Additionally, when I built my latest box, I put two drives into a RAID config (cheap), set them to stripe, and zoom. Much better load times. Alot of motherboards that take SATA drives have RAID-0 support built in as well. Basically, those are the two "bottlenecks" I find most people come across when they like to game (as they usually have a good vid card and processor).
