Three monitors. That's "20 more FPS" at three-monitor setup on maximum settings. And it's 3-way, not Quad.
For three-monitor setups "20 more FPS" is actually A LOT, since FPS falls drastically with each new monitor added.
Of course, that still doesn't justify the pricing of this GPU, but a setup of two Titans would cost less than a setup of two best 690s (EVGA's HCS), which, in my opinion, is better.
That's still a lot of money, but I can see what Nvidia tries to do there with releasing this.
