While chasing specifications and performance numbers of the upcoming GK104 Kepler based Nvidia GTX 680 card, we kinda overlooked one new key feature, multi-display support for up to four independent displays on a single card, another first for Nvidia.
It is pretty much well known that the upcoming GTX 680 will feature two DVI, one HDMI and one DisplayPort output, but for the first time, Nvidia's GPU will be able to drive up to four displays at the same time. Another novelty is that Nvidia's 3D Vision Surround with full stereoscopic 3D on three screens will also work on a single card.
With multi-display support and boasts of good performance per Watt, Nvidia has certainly managed to surprise us this time around. [Yes, they borrowed a few AMD ideas, and now AMD will probably start borrowing theirs, like rebranding. Ed]
