I'm running with a GTX 980ti with everything maxed 1440p.
My FPS at times would drop below 60 which is not ideal, at all.
Also running with a G-Sync monitor so dropping below that FPS wasn't too terrible but still wasn't that great.
Instead of turning graphics down I actually turned OFF "GPU Memory Restriction" and now I do not ever go under 60 FPS and I always hover between 70-80 in demanding segments. If you have a high end video card with a lot of VRAM turn this setting off, it's much better.
