this card be simply awesome . and ye the shader CAN be unlock . Watch a tutorial and just be sure that the bio switch be on the correct position . I have see review say this card be mid range , WROOONG . its not , this card be AMD ATI top of the line at the moment , single gpu -lrb- second to 6970 -rrb- \* the 6990 be dual gpu \* . the card its a great bargain , consider you get a great customize heat sink and double fan -lrb- almost no noise -rrb- , great overclock potential and dual bio . also two game include : Deux ex : human revolution and dirt 3 : a $ 100 value - for free - . I receive the instruction to download Deux ex , two day after I make the order . now , the problem people be have receive the Dirt 3 code , its cause the damn hacker break into the codemaster database several week ago , and steal Dirt 3 serial number . that why AMD be ask people to scan the coupon and send it by email as a extra step to validate you game . resume : want a top of the line video card at a good price , include a great game combo ? get this card . nothing right now can beat this offer . the best video card I have own .
