I'm a hardware caveman like I said, but setup has 2x 500gb 32mb cache drives (they were only about $120 a pop I think?). All of my games/fun shit are on the second drive as was suggested to me and I feel like I could load another 2 or 3 WoWs without problems. Q6600 with 4gb ram.

Just a baseline for ya I suppose. Sounds like ram or more/better drives?
