Hey! I just updated my 7950 TFIII to the new Boost BIOS. However, when I overclock it, the GPU doesn't scale when I run Furmark and 3Dmark11. I get 30FPS on Furmark (1280X720P) when I overclock it, but I get 60FPS at the default 925MHz clock speeds.

You have to use the CCC to overclock the new 7950 boost editions until the overclocking software like Trixx updates better. I am at a very stable 1050/1475 overclock using the CCC.
