Here's a route you can take:
The only drawback for the GPU is it is a KR model with 2 year warranty. The AR models have lifetime warranty, but I could not fit in the budget. Luckily, it is an EVGA card, so you get great service and their forum is full of people waiting to help you out with any issues.
SeaSonic makes solid, quality PSUs, and the one chosen is affordable and is enough to run your system. JohnnyGuru gave it a 9.7 rating, the only con being the zip ties around the cables which you can remove
Also, considering The Old Republic is more GPU bound, and you will have-if you buy it-a high-end GPU paired with a good dual core, you should expect great performance. Tom's has an article about The Old Republic performance analysis. Though your GPU is not mentioned, just look at the GTX 570 and remove about 10 FPS (15 FPS MAX).http://www.tomshardware.com/reviews/star-wars-gaming-tests-review,3087.html
