I'm looking to buy a Macbook Pro and have a price limit of $2000. Will any of the models be able to play Starcraft 2, Diablo 2(didn't work on my White '08 Macbook), Diablo 3(not out, but hoping to get), WoW, and Counter Strike: Source? I'm don't really care about screen size... I care more about performance. Any help would be greatly appreciated .
