Maybe 1080 could cut it.. but two titan x don't. sadly, I was planning only to have two in my HTPC to play games on my 4k TV. Games like tomb raider, the division, and witcher 3 were sub 60fps with only 2. (yes, not including the times when NVidia broke 3-4 way SLI with not putting traffic over the PCI bus .. but they fixed that a few month ago).
Of course playing at 4k and playing at 4k with everything maxed are different things. for me playing at 4k is with all the sparkly stuff on.
