A single 4870 X2, runs 5 x WoW on one screen very well for me. I don't think you'll find a single card on the market as strong, and its in the $600 range. You might find 2x another card in SLI/Crosslink to be superior, I'm not sure on that.
I have the 4870 512 MB from Palit and it runs 5 WoWs just fine. 1920X1200 with keyclone/maximizer. Good 55 fps on the main screen. I have the others set at 20fps max.

4870s (not the x2 model) are hovering at around $220 and up on the major e-tailers. Very good bang for the buck.
