I game on Windows, and uses Mac OSX for pretty much everything else

I regularly play HALO on bootcamp with my friends. Playing FPS with Wireless Mighty Mouse does feel a little bit weird. I reckon it is engineered for web-surfing and other casual usages, and not for gaming.

You could try to contact Machines @KLCC or nearest branch to you. I am pretty sure, they have quite a mouthful of game collections for the mac. Or else, last resort is to bootcamp of course.

I am not sure about PES 2010. But i tried FIFA 09' on the 9400M with bootcamp, and it goes considerably well with all high settings. Well, it is playable in short, with amazing detail. But it fell short, somehow somewhere, sometimes I could notice framerate issues, but it could be ignored, and its not a big deal, as it comes only sometimes during cutscenes, and heavy workload.
