actually they have the driver available already for the 200 series and others but 3 way SLI is not yet supported for the 200 cards but a driver will be released for that.
I am curious as to what would be better for my x2 275's. The 2D surround option from Nvidia or the Triplehead2Go. Triple2go will do support the following for my cards:
The Nvidia 3D option I could care less about but you can get it in 2D
I found the system requirements for Nvidia Surround below which includes 2D and 3D and all gpu's:http://www.nvidia.com/object/3dv-system-requirements-surround-technology.html
So like I said it's just a matter of which will provide me better results across 3 screens gaming the 2D option or the 2Go Digital edition. Obviously the Nvidia option money wise is a no brainer unless you do the 3D.
