Dude, I run WoW at 1280x800 (lowest settings) on my 4+ year old HP. It was $1100 new, and only has a single core AMD 3200+ OC'd to 2.31 GHz, 1gb of DDR ram, and a ATi 200m OC'd 26%. WoW will run on almost anything that's better than a netbook. Unless you tell us what sort of settings you want to play at we really can't help.
