windows drivers don't work so I installed the doom 3 demo in osx to try out game performance. I was playing on high at 1280x1024 with a bit of stuttering. I don't know how to get framerates off games in osx. It was a relatively playable, but I didn't play long enough to get into a fight scene, just the initial walking around the base. I don't know what's normal for that game or how the other mbp's line up to this.
