Everything works fine.

Such as:
* Graphically intense games (World of Warcraft)
* Compiz Fusion effect (Cube, wobbly windows and more)
* Google Earth floats.
* etc.

There is nothing that doesn't work for me.

There was a notification in the system dock that I had restricted drivers that could be installed for my graphic card so I installed them and rebooted my computer. And then it worked.

I don't know if it came automatically, but I do recommend getting 'nvidia-settings' which enables some settings for the graphic card and also shows thermal monitors.
