Hiya, Long life story short, I am a Mac user, but need a proper Windows XP box in order to play hardcore racing simulations; specifically, GTR2. Generally, the advice I get is to avoid dual core processors, unless it's an Intel Core Duo (very fast, but expensive). Getting a dual core anything would mean an equally expensive motherboard, but correct me if I'm wrong. As far as video cards go, a 256 MB 7600GT appears to be a nice deal for performance, but I am hesitant to buy anything 256 MB, because 512 MB looks like "the new standard." What are your opinions? Memory will be 1 gig. HDD will be 80 or 160 gig. These are sort of incidentals, because honestly, I will only be playing one or two racing games, and not use the computer for anything else. I already have a Primary-Use computer. Any advice, tips, suggestions would be greatly appreciated! Thanks for your time, OT.
