My old PBG4 just stopped functioning a few months ago, and with school starting, I think it's time to get a Macbook Pro. I am however an avid gamer, especially World of Warcraft and Starcraft (II soon), and I wanted to know if now was a good time to buy a 17" fully decked out Macbook Pro, are the GPU's good enough to smoothly run WoW on highest settings? Or should I wait till the next update? Thank you
