G-Sync syncs the monitors refresh rate with the FPS your graphics card is feeding the monitor - thus removing screen tearing and other anomalies that happen when the refresh rates are out of sync.

It doesn't make a difference if your card is renderring at 60 fps with out a hitch, but you can see the difference when the fps drop to 50 or 40. Check out this video: http://www.engadget.com/2013/10/18/nvidia-g-sync/
