One concern:
It may be GSYNC, but since there would be no module it works like Freesync. That is perfectly fine if you understand how it all works, however...
The GSYNC range is not mentioned. Unless it drops down to 24FPS (24FPS to 60FPS asynchronous range) you will not get support below the minimum thus you're back to VSYNC ON/OFF issues.
Previously GSYNC laptops avoided this with 75Hz panels and had a range of 30Hz to 75Hz which worked fine, so hopefully they just have panels now that support 24Hz to 60Hz which again will prevent dips below the minimum from suddenly causing added STUTTERING or screen-tear depending on how you've set things up.
