I have a EAH4870 Dk 1gb running at 750 coreclock and 900 memory on a q9550 2.8 quad core with 4gb @ 800 mhz. I have a 800w PS with both power cords plugged into the video card. I have the latest drivers along with latest CCC, and I get a constant 20 fps in WoW on any resolution, ultra settings. In games like 1.6, I get max 100fps, CS:S I get 150 average and left for dead is not a problem. This was a problem in the past and I stopped playing WoW because of it. Is there any help before I go and buy a GTX260?
