This topic was originally intended to be posted in the gaming section, however I see threads discussing the gaming capability of the 2.26GHz model more often in the MBP section. I was originally going to purchase the 2.8GHz 15" MBP over the 2.26GHz 13" MBP for the sole purpose of playing Grand Theft Auto IV, however I decided against it, and purchased the 2.26GHz model. Today I installed Windows 7 RC 64-Bit in hopes that I could play GTA IV on it, but I had low expectations performance wise. To my surprise, the game ran very well. I captured a video to demonstrate the capabilities of this machine: http://www.youtube.com/watch?v=cHsjzn4jp_4 As you can see, the computer handles it just fine. Of course I am running on all low details, but the game wasn't well-optimized anyways and the MBP is still able to play well. My camera records at 30FPS so you should see a fairly accurate representation of how it performs in actuality.
