even with a gtx560ti you wont run max settings at 32 fps everywhere u go. you will run 30-50 fps average, but there will be areas where you drop to 25 or less sometimes, just bleeds in the programming. i just built a new rig from i buy power and went with dual gtx 560ti overclocked and 2gb ddr5 onboard... i dont expect it to max out swtor everywhere, but it should run battlefield3 max settings at 90fps average. swtor just still has too many memory bleeds to be consistent
edit: another thing you may consider is that eventually you will run into a cpu bottleneck with that processor. meaning that even tho you may be running gtx590's in 3 way sli, you might as well have a 9500 gt because your cpu cant push em...
