My friend needs a new comp for college and his parents won't let me build em one which is stupid. They want buy a complete comp from one of them companies like dell or somethin. which company would be the best? also i think they wanna spend like 600-700 ish and this is for a desktop not laptop. i think core 2 duo is out of the question for that price range so i'm guessing the next best thing would be amd?
