I'm having a problem deciding which cards I want to upgrade to. Right now I'm running 2 xfx 8800gs cards in sli. The reason that I chose to run sli is because I run my games at 1680x1050. I don'y know whether to upgrade to 2 BFG 250's or 2 BFG 260's. I've heard good thing about both and the price difference is a lot. I really don't want to spend a whole lot but am looking for something that I can keep for a while. I play alot of FPS, Driving and flight sims. Any help would be greatly appreciated.
