(3840 * 2160 * 60) / (2560 * 1440 * 120) = 1.125
But you're definitely right -- if you have the horsepower for 1440p@120Hz, you have the horsepower for 4K@60Hz. A dual Titan would pull it off in many games.
Slower games such as simulators and RTS probably works just well at 30 frames per second, so you would easily only need a single Titan for that sort of thing at 4K.
