I'm talking about sli and high resolutions.
Obviously the GTX 690 is better at normal gaming, but it's just that the Titan, a single GPU card is able to keep up with a GTX 690, a dual GPU card which is fantastic. It's like they packed the GTX 690 into a smaller card.
The Titan was made to handle huge resolutions and take huge advantage of sli.
A tri-sli or even sli Titans will be able to beat quad-sli GTX 690.
I mean there's even instances where a single Titan will be faster than tri-sli Titans.
And no I'm not trying to hate against the GTX 690, it's definitely the fastest card out there today (not counting workstation GPUs), but the Titan can keep up without a sweat.
But both cards are way too overrated.
