I agree go with the Athlon IIx4 if you intend to play any other games ever. But if you are buying just for those two, the Phenom IIx2 is your best choice.
Edit: Isn't WOW one of those games that keeps changing? Does this not mean at some point perhaps it will be more core optimized?
Yeah thats why I was thinking the Athlon II x4 might be better in the long run. Also the call of duty games for PC (at least world at war to my knowledge) have a multi core rendering option in the graphics menu.
