Weird resolution. I don't see how this would be good for movie rendering, since none of them use this kind of AR :/ Moreover, there isn't an integer width for 16:9 with this height.
edit: Now, this makes more sense:
supporting a maximum resolution of 3840x2560 pixels across four screens
That's 1.5:1, or the same AR as NTSC (720/480) ((9/16)*3840
: The proof is in any CGI movie you see. Ever see aliasing in them?
That's because they use these cards, which are pretty much the same except they use much higher antialiasing/anisotropic filtering, and some even offer double precision (64bit) float calculation.
Basically, that means for irrational numbers like pi, double precision calculates up to 64 numbers after the "dot". I think gaming ATI cards already have double precision, but IIRC NVIDIA cards are still only 32bit float.
Assumptions are bad for you. proper explanation
To get a good example of this, download the NVIDIA DX10 Human Head demo and force antialiasing and anisotropic filtering to 0 in the control panel.
Take a screenshot, and compare it to the application controlled settings.

Their accuracy also allows them to create more natural motion blur.
Game motion blur (like in Crysis or MOHA) is created by first rendering the original scenery (which is aliased), duplicating areas near the center and overlaying them, going outwards from the center, in the opposite direction of the direction the screen is moving (e.g. if you go up, they go downwards).
Now, game motion blur is created from aliased and very sharp graphics.
I remember when I first played MOHA and Crysis, I felt the motion blur was very disorienting.
It's because sharp motion is irritating to our eyes - but we've already gotten used to it from past games. Having partially blurry and partially sharp motion blur feels weird to some.
Since these cards eliminate 99% of aliasing, the motion blur is perfect, and looks much more real.
I've upped a small cut from Appleseed (25 sec, and nobody yell copyright infringement - it's under 1 min, fair use applies). Pause when the fast truck passes by the police officer and he jumps to the side
P.S. I don't think the "PCB changes and small modifications" have anything to do with it. Perhaps they're there to allow for a higher output resolution or different/more connectors, but the changes that affect quality should be 100% driver-related.
