I choose to buy this one because of the 2bio setting and it can easily unlock the shader into 6970 . but it look like the new version -lrb- from first week of 2012 , the time i bring it -rrb- can not , no matter i flash it myself or use the magic switch on the card . CAN NOT UNLOCK the shader . I get the replacement , same issue happend there . if you want to buy one with the really unlock shader , find a use one maybe a good choice . I look some of the review on the Newegg , same issue happend . the new sapphire dirt 3 edition can not unlock shader anymore .
