ConclusionAt $650, the GeForce GTX 780 is designed to make GTX TITAN owners want to kick themselves. At $1,300, for just 30% more than a TITAN, the GTX 780 SLI scores a healthy performance lead that makes spending the extra $299 worthwhile.
The SLI setup scales in most of our games and does so well in some of the more popular ones, which is expected of NVIDIA as it enjoys a better reputation with multi-GPU software support. The company aggressively ships out SLI profiles and beta driver updates whenever a major game faces SLI issues.
Our testing shows that any display setup below 2560x1600 (or 2560x1440) won't do justice to the GeForce GTX 780 SLI configuration. The setup makes sure your frame rates stay high at 2560x1600 comfortably, even letting you crank up anti-aliasing. 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. This alone should solidify GTX 780 SLI's credentials for upcoming 4K Ultra HD display setups. At the moment, most Ultra HD displays cap out at a 30 Hz refresh-rate due to limitation of the HDMI interface, but that should change this year.
In all, the $650 pricing of the single card, which isn't much slower, and the $1,300 pricing of a pair of them, which is significantly faster, should be enough to cannibalize the GTX TITAN. Our heartfelt condolences if you bought one recently.
