the 7950 is capable of close to 60 fps. http://www.tomshardware.com/reviews/radeon-hd-7950-overclock-crossfire-benchmark,3123-6.html
the 6300 will work well with that card, but it may help to push it to 4.0 ghz instead of 3.5 stock.
I only have a 500w psu so I don't think ocing my CPU is possible in all reality. Is that fps number stable, min/max, average, etc? Thanks for the answer too
