I am now assembling my Eyefinity setup. On their way are 3 Dell 2007fp 1600x1200 monitors and the required DP->DVI adapter to make Eyefinity work. I have not yet ordered the video card. I had planned on getting a 5850 but I'm worried that it won't have enough horsepower to drive my display at playable frame rates in MW2. Does anyone have experience with a 5850 or 5870 with an Eyefinity display this size? Should I shell out the extra dough for the 5870 or will the 5850 get me there? I pretty much play only play MW2. The rest of my usage is business stuff (needing lots of screen area) and tracking music (also benefits from lots of screen area).
