Not quite Tamz. Remember that you are dealing with Nvidia here, so the naming will be off. Nvidia Surround is the Nvidia Equivalent of Eyefinity. 3D Surround is the same thing, but in 3D. Here is a good article on this tech.
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.
