How useful is G-Sync with 144Hz monitors?

[smartroad]

I mentioned in another post I am replacing my current monitor setup with some new screens. The original thought was to replace the 3 x 21.5" HD panels with 2 x 27/28" UHD screens. However I also game, and while my GTX1080 can pump out 4K it is at a compromise of FPS and/or quality. So I was thinking of getting a 1440p screen for gaming and a UHD for productivity/video etc. One thing is refresh technologies. Is G-Sync really that good? I mean I can get a non-GS display for £50-100 cheaper than its G-Sync brethren, and even less if I swap brands.

 

I am not a major FPS player, maybe the odd bit of Deus Ex or Half Life, but mostly I play RPG's: Dragons Age, Witcher - although I do play Elite Dangerous but mostly in VR. Or could I get by just by lowering the resolution I play with on the UHD screens?

gsync doesn't discriminate against refresh rates

its inclusive of all the hertz

But visually would I notice? How would say V-Sync work if it can't keep up with pumping out 144FPS

G-Sync only operates when your framerate is below your refresh rate. The higher your refresh rate is the better, you'll be making use of G-Sync more often.

That doesn't make sense to me.  How can it only operate below framerate, but also be better at higher framerates?  Surely G-sync is doing far less work the higher your refresh rates are, because a soon as they go above your refresh rate (according to you), it doesn't function anymore?

 

I'm not saying that you are wrong by the way, but just that I really don't understand your explanation.

I think he means the higher the display refresh rate is, the more g-sync will be of an advantage when the games frame rate is low. So a game at 45FPS will use GSync more with a 144Hz screen then a 60Hz screen.

Okay that does make sense, that's how I thought it worked, so cheers for that.
