It's with the triple-monitor 5760x1080 (3D Vision Surround), where the GTX 780 SLI really shines, as the second card provides a performance cushion that doesn't allow frame-rates to drop below playable levels on some of the more visually intense titles, such as Crysis 3, Battlefield 3, etc..

The card is also almost inaudible in idle, which is great if you work a lot and game rarely.
