As soon as I saw this thread I knew I had forgotten to do something.
I think this is actually an 8800GT wide bios update, as a couple weeks ago BFG did the same thing for their low end OC card, which you can get right
HERE.
A word of warning: there have been many complaints with BFG 8800GT OC/OC2 cards as it seems that BFG used cheap logo stickers on their fans. I know... sounds ridiculous, but apparently the faster speed of the fan is forcing the sticker to slip off. Since the fan is sucking air in the sticker gets sucked into the fan, and sure enough, it seizes up.
The advice is: if you are going to up the speed on the fan above 75%, as well as use this bios update (which can increase the fan above that), remove that sticker regardless of the brand of card.
I sure hope it doesn't void my warranty to remove that sticker, cuz that would just suck @$$ if it did.
