^ I agree with ct1615. His experience in WoW pretty matches mine with several different systems. He won't be MAXED out, but he will get very good performance everywhere but the massive PvP battles in Wintergrasp. Set to "custom", settings to shadows on medium or a bit lower. Other settings either max or down a bit, adjust settings till he's satisfied with fps/visuals, he should be pretty happy with the HD4670. He could get better cards, but he'd start running into +cost or +power issues.
