my head is going crazy thinking about upgrading my computer. which mobo, which processor, hdd, ram, ect. just a moment ago, i figured that if i could compare my computer now, to one i would like to purchase, and see how much of a difference there is, i would know how much i really need to spend, and what to buy, to get to the performance im looking for. anybody know of a site that lets you configure two computers, and have them "compete"??
