Is this spec good enough for gaming?

dont listen to others who are dumbing down your 8800gtx, the card is perfectly fine and can run crysis 2 at high settings at around 1650x1050 or something..currently I am running the game in hardcore settings on my dual core e5200 @2.9ghz and gts250(which is a rebranded 9800gtx/8800gtx) with a playable fps of 39-48..at any rate your quad core processor should do better then my dual core..so go ahead with confidence and try out the games (Y)
