Got this card Dec 1st and be thrill to see that it have the bio switch . I plug it into my rig and it be good to go . I flip the switch and the shader unlock by themselves . I do not have to do any thing but flip the little switch . two of my friend also buy this same GPU , one off of the egg , and the other off of Amazon . both of they gpus unlock exactly like mine do . for those of you who do not know it be located on the top of the card , by the crossfire connector underneath the plastic heat sink cover . take I a while to find it , but it work great . for bf3 I run it unlock and at 950\/1350 @ 1120 in Sapphire 's TRIXX software . this make it so easy to turn it into a 6970 at $ 100 cheaper . at default high setting for bf3 I get 40-80 frame a second . most of the time it be at 60 , but when alot of thing be explode or fall down it drop to 40 . have not see it below 40 though . I also play wow @ ultra and get great frame -lrb- 60-100 -rrb- . although wow be more CPU limited than GPU limited , a upgrade to my processor will help my frame out alot . for $ 220 after rebate this card be a great purchase . my rig : CPU : 955 be GPU : 6950 2gb sapphire -lrb- non dirt3 edition -rrb- case : Corsair 500r white PSU : Corsair tx750 v2 mobo : Gigabyte 990fxa ud3 RAM : 8gb G. skill ripjaw x series
