pro : - quiet fan . they be pretty much silent when compare to my case fan which be quiet . this be my first silent card . this be my biggest selling point . I love it . - Cool . under load this card never exceed 65c . - backplate . not a big deal . look nice . add a little more stability . - higher quality component compare to a reference card . for example , compare the heatsink on this one to a reference heatsink -lrb- look up picture with google -rrb- . - fast . my card boost to 1280mhz out of the box . the base clock on this -lrb- 1058mhz -rrb- be faster than I be able to overclock my reference evga 670 -lrb- which also have annoying fan noise -rrb- . con : - my card have no headroom for oce further or it crash . my max clock be amazing however and it be stable . and I will not complain , in fact I be delighted to get the speed that I get . - GPU Tweak Software by Asus be not so great -lrb- I never bother to use it -rrb- . - pray that the card do not fail because then you have to deal with ASUS 's customer support . they make great product , but they support be terrible -lrb- to say the least -rrb- . other thought : it be a fact that some pre-overclocked card be unstable because Kepler gpus boost so high . I think ASUS be ask too much of some of these GPU 's -lrb- perhaps because of a supply shortage -rrb- . not all can stably boost to mid to high 1200 's . if you be unlucky and do not get a good GPU , it can be unstable and crash under load with certain application . its all the luck of the draw . Mine be terrific and exceed my expectation so I can not give it anything less than 5 star . some people report `` Red Screens of Death '' RSOD 's . it be my understanding that the problem be cause by certain GPU monitoring software . if it happen try different software -lrb- for example evga 's precision x -rrb- . Asus update they GPU tweak software and we 'll see if it fix the rsod problem . I imagine that some of the problem with instability that people be experience may be a bio issue or a problem with a certain batch . we can only hope that ASUS address this in the future . Amazon 's return policy be the best . if you need a rma because of a unstable clock , get a exchange through they . underclock you card until the replacement be ready . then see if you be lucky with the second one . or you could always get the non-overclocked ASUS non-top 670 and overclock it yourself . I probably would have go that route if Amazon have they in stock at the time I purchase this one . in short , if you get a stable card , you will have what be , in my opinion , the best 670 card on the market right now . if you get a unstable card , you could be frustrated -lrb- keep you old video card around for awhile in case of problem -rrb- in my case , I be very happy . UPDATE : my card still run fine . for those who be worry about issue or be have issue . ASUS have release new bio on they website that supposedly resolve problem with the card overclock too high . that should alleviate some concern about problem with the card .
