I think you should go for the 7950. It has got a low TDP and a much cooler as well as low-sounding fan. With that in some games you get better performance than the 760.
completely wrong, 7950 is more expensive and about 5-10% weaker than the 760, it also is noisier.
Go for MSI GTX 760 TwinFrozr Gaming, very quiet, very cool, and much better than EVGA's version of GTX 760
