hi, i currently have a gtx 670 love the card but want more, i'm running a i7 3770k,16gb corsair vengeance ram, xfx 750w psu, ga-z77x-ud5h motherboard, my temps are very good at the moment and i would like to keep them that way the gtx 690 has 10% more performance than the titan, but what other issues are there and which card would be better as there are about the same price ???
