If we reached that point gsync would not be needed. Gsync comes into play when frame rates drop BELOW the refresh rate of the monitor. When framerates go above the refresh of the monitor then g-sync acts just like v-sync with the included input lag. The trick to getting the full potential out of g-sync is getting a frame rate slightly below the refresh rate. Thus running @ 144hz you should be limiting your games (via ingame fps cap commands) to something around 130fps. With this setup you will have zero input lag, no graphical stuttering, and the smoothest possible gameplay experience for your setup. As the frame rates can drop from 130 down to 60ish and you will not experience any stutter. However 60fps is still 60fps and will feel different than when your game is running at 130fps. Understand that there are many factors involved including the game (and how well its coded to handle rendering), your entire gaming rig and of course your video card's muscle that will dictate your frame rate at any given time. The more complex the scene or frame is to draw, the lower your frame rate will go and thus g-sync will allow the GPU to dictate what refresh rate the monitor displays at. This will create a much visually smoother gameplay experience as every frame, no matter how fast it's getting sent to your monitor will be displayed.
