“Despite the stupendous performance of the GeForce GTX 690, some gamers are destined to clamor for more. That's where Quad SLI comes in. When two GeForce GTX 690s are connected via an SLI motherboard, four GPUs work in unison in Quad SLI mode. Each GPU works on a distinct frame for a total of four frames in flight at a given time. The resulting performance is simply otherworldly.
In Battlefield 3, at 2560 x 1600 with all settings maxed out, the framerate exceeds 120 FPS. Crysis 2 runs just shy of 100 FPS. And in the most demanding game, Metro 2033, the performance scales almost linearly to reach 56 FPS.”
