If you plan to play in 2160p no. Especially if you are on low FPS. I survived with a 780Ti/1060 3G more than a year and it helped a lot. 45+ FPS look smoother, everything above 50 FPS doesn't make a difference anymore.
Note a 1080Ti does only get 40 FPS in 2160p if you play the newest titles with max details.
Is this the Gaymer Nexus Sup Forums official account you people keep talking about?
the purpose of freesync and gsync works identical
what differs though is the requirements nvidia makes for gsync approval. which is a higher quality scaler you pay extra so you have a larger sync range
forgot to add:
while on freesync the manufacteurer can decide the quality of the scaler,
the Asus MG279Q for example uses the same panel as Eizo Foris FS2735. but use inhouse software and scaler
the eizo manages to natively have a freesync range from 35 to 144hz while the asus covers "only" 60 to 144
This. The only difference is a proprietary module. Some hackers once found out Gsync does work without one, with a hacked driver. It should be known that laptops doesn't use a module, but they also use eDP.
