2.4ghz C2D, 4GB RAM, 2010 MBP 13" unibody - I installed windows xp w/ sp2 via bootcamp. Then i installed Starcraft 2 onto bootcamp'ed windows and ran it using: - 1280x800 resolution - all graphics settings on medium (~75%)/low - all sound options on medium(~75%)/low The bottom line is this: running Starcraft 2 on medium was a good experience. I do not get to see every single dust particle/armor chink nor do I hear individual footsteps/gust of wind. That's not my point- my point is that when I bought my MBP 13", i had no intentions of running a game like Starcraft 2 on it; at most I was expecting to play Minesweeper or Chess. I was very surprised that the 13" handled SC2 like it did (lag is almost nonexistent except with the heaviest of scenes aka 60+ animations). The 13" MBP is powerful enough for any casual gamer, and I do NOT consider SC2 a casual game.
