try hooking both monitors to the same(primary) card, frame rate aare dropping because windows is software renderign from your second card eating your precious cpu cycles.
This ^ ^ ^

If you're using a program like InnerSpace you can tell WoW which card to launch on. You can manually do but I forget how...it's on the forums here somewhere. I think the only real reason to use more than one card [with 2 outputs] is if you're trying to hook up more than 2 monitors. Especially with 260's...I have a GTX 260 myself and I'm 5 boxing like a champ.
