Vertical sync
Coming from a pc gaming background it sounds like you have vertical sync enabled. What that does is try to limit your fps to 60fps to match your monitors refresh rate. The disadvantage of this setting enabled is sometimes the frame rate will drop below the 60fps into the 40 range.
Disabling it should crank up you fps to at least the 80s, but then you might get something known as tearing which you'll a horizontal line where the frame doesn't line up. That can be annoying but when benchmarking a system the non-vsynced numbers are usually more significant. Play around with the option and see what you like better.
I'm weird in the fact that I have PC for gaming and a MacBook for my laptop. I probably won't switch the PC out until Mac comes out with a cheaper tower. Mac Pros are sweet, but I really don't need that much power and iMacs are still under powered for the price when I don't want that form factor.
Portal and TF2 have been running great on my i7 MBP (330M GT). Portal gets a constant 60fps, with a drop (not too noticeable, just to 40-30fps) when you look into an open portal. TF2 runs great, but I didn't check the FPS for it. I can't wait till it goes public. I really want to replay Half Life 2.
Both games on medium-high settings.
