My vote is for a 6850 everytime i see someone wanting the best card for 100 bucks. Yes, its a little more, but the bang for the buck on this card is unbeatable currently. A GTX 550Ti is the similal nvidia card on the price point, but I feel its performance is inferior after reading reviews and many benchmarks. I am hesitant to recommend the 6xxx series cards however after so many people experiencing problems with swtor currently. Yours may run just fine if some of the software for the game is tweaked in upcoming patches. Also, your problem may not solely be video card related as your processor or bus could be bottlenecking you.
