I recently bought Starcraft II only to find out that it won't run on my late 2006 iMac. I need a computer upgrade. Will Starcraft run better on a lower clocked multicore computer or a higher clocked single core or fewer core computer? I may consider building a Windows box but more likely I would stay with Mac and would consider the 2.8 gHz iMac quad core, 3.2 gHz single core iMac, or 2.4 gHz octo core Mac Pro. Given what I've heard about the bad Mac drivers, I would most likely run it on Windows using Boot Camp. Thanks!
