V-sync synchronizes your fps output to the refresh of your monitor. Not having it on just shows actual gpu output, but since your monitor is a 60Hz refresh, the monitor itself will limit the fps to 60. V-sync can help if you are experiencing any issues such as artifacts or tearing caused by too many frames trying to be shown but a monitor that's limiting. As long as your game play is smooth, it won't hurt either way.
