I'm running AMD FX 6300 @4.0Ghz (Black Edition) and Ge Force GTX 2GB 750ti Superclocked at 1150Mhz, 8gb DDR-3.
There is absolutely nothing wrong with 6300FX CPU. It overclocks like a champ, costs 80$ and for its value/performance it beats i3 any day, any game.
I run SWTOR at 1920x1080p all settings on HIGH with shadows on medium, other settings enabled and average 40-45fps anywhere on the map and 35 average in main cities with lots of people around.
For the money FX6300 costs you can't go wrong, pair it with 2GB 750ti and you will have a great time in SWTOR without breaking a buck.
