I was waiting to buy a new Macbook Pro but as soon as they were released today I said "meh" and decided maybe I should buy a brand new iMac and keep my Early 08 MBP. I want to get a new Mac in preparation for the upcoming launch of Steam on OS X and just because mine is long in the tooth for Windows gaming. Anyways... I just had a thought and was wondering if any owners could clear it up. The resolution on the 27 i7 Quad Core seems ENORMOUS for a middle-grade ATI GPU. Are you able to game on high settings for semi-modern games like L4D2, TF2, etc. at the 27"'s native resolution? What are your thoughts on it as a gaming machine. It seems like the 27" will obsolete itself quicker than a i5/i7 21 inch (if one ever comes out) due to the screen resolution size.
