I just bought a ASUS HD 3850 256mb and I'm loving the card ATM(beat the crap out of my old 6800 gts). I'm getting a new CPU, mobo and mem asap. I was wondering should I get a CF mobo and hook up 2 cards? If I do that then I got some q's. My main questions are: Can I buy a 3870 and put that to work with my 3850, and will it be better than 2 3850's? If I buy the 512mb version of 3850 and use that as my "main" card, will it work better than having 2 256mb versions? Thanks in advance.
