I have always use AMD because of the lower power consumption and know my way around they driver very well . I buy this for a new build I just do , but the card be extremely unstable under it be stock configuration with the most recent driver , even before I even attempt overclocking . build quality be excellent and temp be really low , perhaps lower than any of they card I have use before , but even when not overclock on the stock bio all I have be issue like artifact , and black screen . test it in another computer and it have the same issue . just for kick I try to unlock the shader as well , but it look like they have be laser off of the newer batch . it be unfortunate that I get a bad card , but I have decide to go with the xfx hd7970 instead and hope that it live up to the hype . I be sure that most of these card work just fine , mine probably have some bad vram . accord to many review this card when work can play pretty much any game on highest setting with a decent frame-rate , when overclock it be suppose to do very well . I be get a average of 90fp in Starcraft II on highest setting at 1920x1080 when slightly overclock , and when use 2560x1440 resolution I be get on average 60fp as well , again slightly overclock . I do not get to try it with any other game because it just crap out on I on the first day . honestly this card be great for most gamer except maybe the hardcore enthusiast , just stress test yours and make sure it be work properly .
