go to www.srtest.com and just select Star Wars battlefront 2 to see if you can. I can't judge well just based on a video card. The only thing I could say about it would be you'd have to put it on low settings.
C00l i might buy 2142 once it's released tried the demo pretty stable graphics even when i put in High/medium on my card...
But on topic-The game should run fine just dont get into 64 player battles..
