I originally be go to purchase this on Newegg , but they sell out . Amazon to the rescue ! I buy this card as a replacement for a burn out 5870 , so I be not see a huge improvement , but the hd 5870 be already a great card so I be not expect too much of a boost . that say , this thing run anything I throw at it . I cheap out and go with AMD for a CPU , so I do not ULTRA MAX EVERYTHING like some people be able to with this card , but I can run Skyrim at 40-60fp on Ultra High Quality with 8x aa and 16x af , and Crysis at very high at 30-40fp with 4x aa . these be about 5 to 10 frame higher than my 5870 be run they at so , I be happy with it . I do not have battlefield 3 yet , or I would test that as well . Arkham City run great if I leave dx11 off , though this be more a issue with the game than the card . for unlocker : the card that I receive doe have a bio switch on it , but I could not get it to unlock the 6970 shader . I have read that some people have have success with it , but after work with it for a few hour , all I get be a card that would crash and produce major artifact with any bio other than the original one . I be still satisfied though , because I 'll be crossfire these by Christmas next year , with a i7 cpu hopefully as well . : -rrb- overall , I be quite satisfied , provide this one do not die in a year and a half like my 5870 do . I 'll update this review if it do , or if I have any other issue with it .
