My current spec is latest: i5 3.1GHz 4 GB Ram HD6970m 1GB 1TB Hdd Running StarCraft 2 on max resolution makes the game impossible to play. Running it on HD res with all the details 1 notch from the best (high or ultra) again makes that game impossible to play. Even when I drop all the details to Medium and HD res game still does some slideshow especialy just before animating all the explosions. Not sure what's the story here, poor GPU, not enough RAM ? That's a good reason for me to return that imac tbh. Not that I am a mad gamer but on the other hand SC2 is not some kind of Crysis type of stuff.
