Mind providing a link? I could just be blind, but I can't find it.
Also, wouldn't running 2 monitors on the one card be kinda harsh? I've run 2 monitors off 1 video card before (granted the video card was pretty bad compared to the 8600) and I couldn't even stay connected to WoW on lowest settings because it would drop the frame rate down to about 0.5 and the game would crash...
