Ok for some weird reason I am deciding to remodel my system (maybe out of boredom or something), any ways on my current system I own a single Nvidia 8800GTX. I have been hearing a lot of hype about ATI's new line of Radeon cards, specifically the 4850 and 4870 series. My question is, would dual HD 4850 cards be better than my single 8800GTX? I am liking the pricing on those cards, and depending on the prices of 4870 series I may consider it too.
