I'd expect Futuremark to have something ready first, but the Unigine Corp. has created the world's first DirectX 11 benchmark. This isn't something like Battleforge (the world's first DirectX 11 supported game), this actually does do a few DirectX 11 only things, the most obvious being hardware tesselation. If you have Winodws 7 fired up and are one of the early adopters of the Radeon HD 5000 series, give Heaven a go.
