Just tried it on Skyrim. 2D used ~830MB, 3D used ~1020MB. 1080p, High Quality, same scene in the game.

We're talking about 3D Vision on a single monitor, not NVIDIA Surround.

While there is an increased use of memory in 3D, it's nowhere as near as what Surround needs. As far as I'm aware, the processing power of the GPU is what matters because it's having to render left and right frames instead of a single standard frame.
I'll have to look at benchmarks of memory consumption in 3D on the 680s now, thanks for bringing that point up, Pontiac.
