Navagon: I have a GTX 260 running (presently) on XP with minimal background crap. So that probably helps.
The best hope for Star Wars will come when Lucas no longer has anything to do with it. KotOR proved that many others have far better ideas of where to take the IP than Lucas' increasingly childlike approach. Once someone who respects the original trilogy takes control then we could see something of a Star Wars Renaissance.
No wonder, I use a GTX295 and Vista, installing to 7. Well, it's done now, so I'll try out my games to see if I system performance bump.
Anyway, I totally agree with what you're saying about Star Wars. Right now, it seems like there are the guys who have a good idea about Star Wars (see KOTOR, TOR, Battlefront and those games) and the guys that have no fucking clue (see TFU, Republic Heroes, any film-based Star Wars games, Galaxies). It's like a giant fork.
