Only do it if they are willing to charge you less for it. Id say the 670 and 760, for all extensive purposes, the same, and when you overclock the 760, it should perform better than most stock 670's. That being said, a 760 is around $250, a 670 is around $330. So I'd only go with the 760 if they were charging you less for it. If they are charging you the same amount, go with the 670 and overclock that sucker. But keep in mind a one thing tough: the 700 series of cards comes with a built in h.264 encoder which enables shadow play (screen recording with very little hit to your gaming performance. Anyone who uses fraps for recording knows how detrimental to your framerate fraps recording can be). This may or may not be important to you.
