From what I've heard, the Titan X is the best Titan so far, and if you can afford it, can run pretty much everything in 4k ultra with almost 60fps or even higher. Have a look. https://www.youtube.com/watch?v=xsCIdqIqbgM

Just because it was released before the 980TI released doesn't make it outdated, it's still the most recent Titan series card, and he's not comparing the Titan X to the 980TI, just benchmarking the Titan X
While it is the best Titan for gaming, it is not as good as the original for double precision floating point calculations, so it is only better than the Titan for gaming.
However, we are talking about Titan X vs 980 TI SLI. The Titan X is not better than many of the aftermarket 980 TI's alone, much less in SLI.
