Here is a free tool I've found to benchmark your system with DirectX 11, Dx10 and Dx9. With a Dx11 system and this tool you can do a fly through looking at the stone walk way, the shingles on the roof, the ropes on the bridge, and the dragon, pressing F3 will cycle you threw DirectX10 and DirectX11.

Dx10I'm sorry for the bad screenshots. I had an older version of Fraps that didn't work with Windows 7.
Pressing F2 you can cycle the wire frame on and off and while left on you can see the two different wire frames between Dx11 and Dx10. For the best visual demo, watch this YouTube video.
Josh Walrath of PC Perspective wrote me saying:
"Hey Cam,Thank you Josh!
AMD/ATI introduced a Tessellation Engine in their R600 card (the HD 2900 XT) and had one in each preceding generation. However, DirectX did not support Tessellation until DX11. For Tessellation to work in any DirectX application, the card must be fully DX11 capable. So, those earlier cards from AMD will not run these DX11 benchmarks.
Heaven is a benchmark, but not a game yet. The first real DX11 game that came out was Dirt 2, and it did feature Tessellation support (though in very limited situations). Namely water and crowd tessellation. As for how people are doing the Heaven benchmark ... since so few people have full DX11 cards, they test benchmark in DX10 mode. The scores in DX11 and DX10 mode should not be confused with each other, as each has a very different workload."
So, if you want to get your rig up to full Dx11, as of the date of this post, ATI has the only Dx11 card on the market: XFX RADEON HD 5870 1 GB DDR5 PCI Express Card HD587AZNF9
