Im going to be putting together my new system tomorrow, and have 2 different hard drives. HD #1 is a 160GB 8mb cache 7200rpm hd, HD #2 is 80GB 2mb cache 7200rpm. My main question is to due with gaming performance. It's my understanding that it is best to have OS on a one drive, and apps/games on the other. But given my difference in cache/hd size what would be my best options?
