i see the benchmark at youtube website and gtx 580 be much powerful than gtx 570 but between gtx 680 and gtx 670 be almost same performance but 100 dollar less so i decide to buy gtx 670 . im very happy with this compare to gtx 580 -lrb- my previous card -rrb- . if you overclock the gtx 670 will overpower gtx 680 and that awesome ! by the way 3d vision be just amazing and im tell you guy 3d movie suck but 3d gaming be AMAZING because 3d effect be lot more 3 dimension than 3d movie !!!!! too bad lot of people do not even give it a try . 2d flat picture gaming suck !!!!!! update ! !!!!!!!!!! DO NOT BUY THIS model -lrb- 02g-p4-2670 -rrb- it only last me 2 week !!! buy the gtx 670 -lrb- 02g-p4-2678 -rrb- model instead !!! it seem like EVGA fix all the bad problem on THIS NEW MODEL . I read the REVIEW FROM NEWEGG WEBSITE and HARDLY NOBODY COMPLAIN on THIS MODEL I should have LISTEN to those review . IM very happy with the new model
