After going from 1080P to 1440P, it is night and day difference, I will never go back. I've used a 1080p 120Hz screen and yes it's nice but the lower Res is painful. I have a 27 inch Dell at 1440p and a 290X, example of Skyrim modded to look amazing, runs at 40 fps, when it gets up to 60 fps, it feels ultra smooth, almost too smooth. so 120 fps would be wasted graphics power. "oh but what about FPS games" I hear you say. 60fps BF4 is awesome. What needs to happen is gaming 1440p monitors at 60Hz with low input lag and good color reproduction. Omg, color makes a huge difference but that's another story
