I'm new to this forum, but I have decided to build my 1st computer and I'm trying to learn as much as possible so I do it right.
That being said, I too am planning on playing Star Wars The Old Republic and already have World of Warcraft, so doing some research as to which components I'll need, I came across this thread in the SWTOR forums. It's a very informative read and I would highly recommend it.
The video card you listed according to the thread would allow you to play SWTOR, but only at medium setting (for a decent Frame Per Second)

Hope this helps
