Quite far away. Even the Titan X Pascal is having some trouble maintaining a consistent 60 fps in all games.

See the Mirror's Edge and The Division benchmarks. Averages are (just) over 60, but there are dips below.

Personally, I think the best resolution for current-gen cards is 3440x1440. Should be rock solid 60+ fps in all games, and gives the benefit of being ultrawide.
