Linux + "nVidia surround" + 3 monitors?

Is it possible to run 3 monitors on 1 nvidia card (600 series, 640/650/660/670) under linux/xorg with the closed source nvidia driver?

At the moment a have a 2 monitors on my linux system in a twinview configuration and i would like to add a third.

Solution 1:

Because of my new 660ti i can now answer my own question:

Yes, you can use TwinView with 3 (maybe even 4) screens the same way you used it with 2 screens on older nvidia cards (testet with 3 screens: 2xDVI + 1xHDMI).

Solution 2:

As of September 22, 2012, the Nvidia site doesn't list the 650 as "supported" under Linux. The 660ti is supported by driver version 304.43, released on August 27, 2012, so that's probably why the OP has joy:

With luck, the 650 will be in the next driver release.
