Im running three GTX 480, and each of my 22" monitors is connected to a different GPU.
I havent tested yet the "3D Surround", since i had some issues with my 3D glasses.
Running Crysis Warhead and STALKER Clear Sky (some of my favourite DX10 titles), the GPU usage of each GTX 480 stays near from 98 - 99% very often. Not all games feature this usage of course, ill add more tests later to this post.
Its also great to be able to run DX10 and DX11 titles at 5040x1050, what could be done with the matrox adapter, but isnt something new for surround gaming of course since ATIs eyefinity solution.
There are clearly things to improve, games like Arma 2 OA and SC Conviction dont have such impressive performance, certainly due to the poorer SLI support. Also, afaik there is no way to set the windows to maximize only on the central monitor i.e. (like you could adjust in matrox powerdesk), lets not forget that these are beta drivers.
On the other hand, the Nvidia surround performance is "linked" to the SLI support of the game, and you cant run the Nvidia solution with one GPU, that may represent, in some very specific titles, a disadvantage compared to the other current solutions (matrox and eyefinity) that allow the gamer to turn SLI or Crossfire on/off if necessary (ex. Mirrors Edge and occasionally Splinter Cell Conviction).
Anyway it is amazing to be able to play games like Crysis Warhead, on DX10, all maxed + AA4x at 5040x1050, and get around 40FPS, plus checking such high GPU usage.
Btw the bezel management is very easy to configure. :rockout
