Managed to find an interesting video showing, very briefly, the capabilities of the NVidia GF100 in DirectX11 via Unengine.  While the site is in Italian, the translation reads:

We managed to track exclusively for you from a Chinese website on the first video of the new series of graphics cards Nvidia Without dealing with the benchmark Unigine DirectX 11.

To you after the jump to preview the video GF100 in action.

See the video after the break.

Update: Found another better, longer video with narration showing not only the Unengine demo, but video of the open computer case showing the Card & Connections.  After the break.
