GF3 Ti200 64 mb should run the game just fine, as long as you have a decent processor and RAM. I have a AMD 1700+, 512 mb PC2100 RAM, and a GF3 Ti200, and I was running at 1024x768 without any problems.
The only thing that I don't like about the PC version is that there is no way to turn your non-Jedi NPCs into Jedis. There was nothing better than putting Canderous into the Cassus Fett armor and letting him just rip through just about everyone after I put everyone in stasis.
Otherwise, I think the PC version is superior. The game looks better, even when you're running the game at just 800x600. The ability to skip through most of the non-story based cinematics (how many times do you need to see the same clip of the Ebon Hawk being chased by the Sith fighters, jumping to hyperspeed, and landing/departing from a planet? I think I like the interface better on the PC as well, because you go to specific pause menus a lot better as well, and you don't have to worry about throwing a grenade or something when you're searching for a force power.
