<p>runningncircles1 your videocard is a piece of crap. will work very slowly with vista. also, what motheboard do you have? there are no dual-cpu motherboards for LGA775 so you must have just spent extra money on the second CPU.
and one dual-core presler cpu doesnt work twice as fast as the single-core prescott would. not even close.
PS dont use debian. its too much pain in the butt to configure for a beginner, since its developed by enthusiasts and theres no company behind it. i'd say suse is the way to go, although i'd use windows.</p>
