With these specs, of course the x-box. The pc version has some more models, that's it. Why would you prefer pc anyway, star wars needs to be on a big fat tv with a larger then life soundsystem! By the way, IGN has a review of KOTOR 2, and they liked it. Ah well regardless the system, you are in for one hell of a ride! For some reason I neglected this game untill I found a used copy, and now it is the only game that I finished 4 times besides Thief (lost count with that one).
