I was wondering if anyone could post experiences. I am about to pull the trigger on an iMac for my wife, and i was going to save 300$ and get the core2duo processor. Anyone use it for Team fortress 2, half life 2, etc. on bootcamp? I am trying to gauge performance for when they release steam for mac in April, and figure out if I really need to spend extra for the i5 and 4850 graphics. Thank you for all input/opinions.
