Update for anyone who cares:
Point of clarification...this is Nvidia Surround, NOT 3D surround.
I had to add a sound card because, I like a lot of people, just assumed that onboard sound would do 5.1 surround through SPDIF. Anywho, so now I have a Auzentech Bravura sound card.
I wanted to comment and say that Nvidia surround is NOT exactly plug and play. It is not ready for main stream. There is simply too much tweaking and annoyances it seems. Of course, it's possibly just me. With that said, once you get it set up it's awesome!!!! It takes some getting used to, but it is awesome!!
I purposely waited to play Just Cause 2 for this setup and it feels like Just Cause 2 was MADE for triple screen gaming. IT IS ABSOLUTELY BEAUTIFUL. It doesn't hurt that JC2 is one of the best games I've played since Crysis either.
My intent is still to take some video and through it up on Youtube. I'll post links when I do that.
