G-Sync Vs V-Sync Vs No-Sync | Which one is best for gaming?

* Watch High Quality with 60fps to see the difference better. Tested few Games and in the end of the video is Nvidia&Pendulum G-SYNC Test to see which is the best option for gaming. For me right off the bat G-SYNC feels much more smoother and stutter free Compared to V-SYNC AND NO- SYNC. V-SYNC stutters a lot and NO-SYNC causes a lot Screen Tearing... G-SYNC is totally worth it!
