Im tired of waiting for a new iMac and think im ready to take the plunge with the C2D 21.5 high end iMac. I was wondering how well the Starcraft 2 beta runs on it? I might opt for an i5 27inch as Ive seen one going for 1400£ brand new. But the screen is simply too huge for what I want to do - alot of anime watching, and gaming with TF2, Starcraft 2 and Diablo 3 (dont think ill be gaming on anything else).
