I was running SWTOR in the 18-25 FPS range with no video card at all (on my 42" 720p Sony TV) along side a 2nd 19" monitor running IE8, and onboard Intel HD3000 graphics. I had everything maxxed other than shadows (off) and AA (off). The play was smooth, even in heavily populated areas, however, after intalling my 560Ti, I gotta say its nice having shadows on high and AA on high! Now I'm maxxing at 111 FPS but I can't really tell the difference in how smooth the play is; rather, the shadows and AA just make it look better.
You can see how it performs here: http://www.notebookcheck.net/AMD-Radeon-HD-6630M.43963.0.html
And compare it rougly to what I was running here: http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html
I think you'll be pleasantly suprised.
