Haven't done much with desktops in a long time...been using the laptop I got from school. Anyway...what do I need to run COD4 with close to max settings? Honestly though, it will MOSTLY be used for WoW. Everyone's been talking about the q6600 and 8800gt... I need pretty much everything but an operating system and monitor...I dont think i can reuse anything from my crappy 5y/o desktop. Goal: $600 possible? Max of like $800.
