So, my windows box in my signature has been giving me issues for about 3 months now. I've replaced nearly all internals and still lockups, freezes ect. Formatted 4+ times, nothing fixes it. I've come to the point of wanting to wash my hands of it, and im considering a base 27" iMac. Just for basic use, however I would like to be able to play Starcraft 2 on it. Don't care much about other games, frankly don't have time for them. Will this iMac be suitable for that? I don't mind running medium settings as long as the framerate is good. Anything I should know before taking the plunge? I've fallen in love with osx since getting my air... i can get the base model refurbed for 1550 after tax ect.
