If you mean the nVidia 3D vision, then yes the nVidia GTX460 supports this feature. Although you do need to order a "3D Ready" Monitor along with the nVidia 3D Vision Kit in order to get it all working correctly.
I have seen the 3D setup a few times now and it does look good, however not all games fully support 3D. In my opinion, I wouldn't buy into 3D.... yet. I would wait for it to become more "mainstream" where more games/apps support it and when the price comes down a bit. 3D technology is still relatively new so we are all paying premium prices for it!
