Nvidia's 680M reviewed.

[ObserverJLin]

Before I start my post I would like to ask the following. On notebookcheck.net they say 680M is DX11.1 & 7970M is DX11. What is the difference?

I really hope AMD make a sprint on the drivers to make the 7970m more reliable.

DirectX 11.1 isn't much different from standard DirectX 11, except more native support for Stereo 3D (Microsoft 3D Vision type stuff from what I understand) and a few new developer features. In my opinion it is more of a marketing gimmick for graphics card providers at this point as very few, if any games developers are using it, and they may not decide to use it in future if DirectX 12 appears around the corner.
