So has blizzard added full quadcore support to cataclysm yet? You can already set it to use multiple cores atm but it doesnt really do anything. Im running a phenom II X4 be at a 3.6ghz and i have 2 ati hd 4890's with 4gb's of ram. Its pretty annoying that i get fps dips in wow in some locations because one of my cores maxes out. I really hope they add this.
