For anyone interested here's the download page to the Unigine Heaven DirectX 11 Benchmark, you can run the benchmark using DX10 but you don't get the Tessellation feature.
 
 

That video is stunningly beautiful. 

that video looked better than real life

That was pretty good.

Some of the best looking vegetation I've seen, very nice

wow even the music is awesome, totally kept me mesmerized

I'll definately run this whenever my 5870 arrives.

The cobblestone paths and whatnot looked awesome! :D

Those paths and bridges look really inconvenient =p

@Diamond: Maybe in a year or two. The games I want that have DX11 stuff aren't using it to as great effect as that benchmark. The DX11 stuff in DiRT 2 and STALKER: CoP isn't as impressive. It's cool, but not cool enough to jump to Win 7 and DX11 over (might as well do both at the same time). Clear Sky runs great, so I'm hoping to get similar performance in Call of Pripyat. If not, I'll live...for a year or two. :P "

Looks great, hopefully it'll be used for games, not just benchmarks.

Too much DOF for my eyes. :/

This i what Fable 3 should look like, too bad i won't.
