let I start out by say that I have purchase this item from Amazon , but I be go to exchange it for another one because this card be so good . I be get a lot of bsod and have be post on forum to try to figure out what be go on . I go so far as to reformat my computer and I be still get the blue screen . this card be fast and quiet . let I emphasize how quiet it be ... you never hear it over you normal pc fan . maybe I have not play it long enough or oce it enough to really make the temp high , but still it be pretty amazing that it be so quiet . my 5870 sound like a jet take off and my 6870 be a little better , but this thing outstanding as far as noise go . as far as performance go , it handle pretty much anything you throw at it . I have not spend time overclock to card to see how far I can take it because of my bsod , but I hear from everyone that it can oc up too 100mhz over what the factory overclock be without any cooling . I can tell you that any stuttering I have experience during game have not be due to the card , and I have prove it be always CPU issue or poor game programming . I be run this in only 1680x1050 and have get 60fp or greater in every game I try out , even Crysis on ultra with 8x aa . the only game that could not handle this card be Metro 2033 on ultra which I keep get 20-40fps while play for my short time . however , pretty much any card have trouble with that game , so I be not go to count that against this card . now , let I complain about AMD and they driver . do not get this card yet if you have Windows xp only because there be no xp driver that support the 7k series yet ! I find that a little ridiculous since I could not test to see if I experience the same issue in xp or not . as far as the Windows 7 driver go , I have have some weird issue with my pc since I install the card as far as window on my pc get corrupted and have random display driver crash . I still can not tell if they be related to the fact that I have get a dud or not , but I see people on other forum complain about various driver issue as well . I would still say that if you be in the market for a $ 300-400 card , this one be it . \*\*\*\* UPDATE 5\/11\/2012 \*\*\*\* either I be a very unlucky person and I happen to get two bad card , or there be something very wrong with this card\/amd 's drivers\/my system . I speak with AMD , Sapphire , and my motherboard company and all of they tell I that my system should run the card flawlessly . Sapphire say they have no other idea and to return the card . AMD say they have ton of test system run all sort of hardware and os , and they claim that they have see no issue with tdr -lrb- display driver do not respond error -rrb- , blue screen , or game freezing . I be experience these worse with my second card , but I also update to the latest 12.4 driver . I try everything to fix this : update my bio , all 3 driver use all sort of driver cleaning program , fresh install of window 7 , update my bio , update my vbio , every setting possible , etc. and every combination of these . I still have constant blue screen , freezing , issue with the clock speed stay at they energy save rate during gameplay , etc. . two other weird issue be that anytime I have flash run in firefox , my AMD overdrive setting would revert to default , and with 12.4 , I would get terrible game performance until I alt-tab the game . I do not know what to do so I be exchange the card for a different model . this problem seem to be localized to a certain subset of user , but it definitely be there and my thread be rather popular on the forum with people all chime in about have the same issue . the card be good , when it work , but it be something I can not deal with . I have spend 80 hour try to debug this problem and lose all sort of work because of random blue screen . I would say avoid this card if you have Windows 7 64-bit and a Gigabyte ga-x58-ud3r motherboard . I never get to test with xp because the driver be not available at the time . \*\*\*\*\*\* special thanks to Amazon for allow I to get replacement card . you guy rock , and Amazon Prime have be a godsend . \*\*\*\*\*\*\*
