Holding 120FPS constant is difficult. 4K benchmarks are not impressive. 3-4 Titans have difficulties reaching >40FPS @ 4K resolutions. I guess driver can improve things. As for triple displays though, I personally get nauseous when playing along 3 monitors. At least with FPS games.I actually considered buying a pair of those to go along with my catleap because they are so inexpensive and people are having such good luck with them... except I feel it's impossible at the moment to have enough GPU horsepower to play triple display at that resolution and try to hold 100+ fps at almost anything.
