What would stop me and others from buying this? Well the 700$ Price tag for one, and the fact that I would also have to upgrade my power supply doesn’t sit well with me… so for right now my XFX 8800GT XXX Edition will have to suffice… hey I can still play Call of Duty Black Ops at 1920×1080 full details at 60+fps. Just goes to show how powerful the Corei5 2500K processor is!
