From this article:

"Then there's the new 3D Vision Surround, bolstered by a redesigned display logic, which addresses the two-display limitation of NVIDIA GPUs. You can now connect as many as four monitors to a GeForce Kepler GPU, enabling 3-monitor HD 3D Vision Surround setups. You no longer need more than one GeForce GPU to connect more than two monitors."

This makes me a happy camper. I don't need a ton of power so I can never quite justify the cost of a second card. However I use three screens for desktop use which left me with ATi as the only option until now.
