2 Questions: Gsync & 75hz Display + Experience

I have 2 quick questions regarding Gsync.

1.) IF a notebook has Gsync, does it ALWAYS have a 75hz display?

2.) Is Gsync worth the extra bucks? Is the difference between 75 vs 60hz noticable? I read a lot that if u try 120hz displays (or even 144hz/165hz) u never want back to 60hz cause of the "softness" even in office work.
And there arent 120hz notebooks, so will I get with 75hz the same experience? Is it worth?

Would like to read some comments before I decide what notebook i get.

Thanks a lot

Sub 4k display G-sync requirement is minimum 75Hz refresh. 4k displays are "G-sync certified" at 60Hz minimum.

Worth the extra is debatable. I find it's a great benefit. It's one of those things that I never noticed screen tearing that much before I had G-sync, but now that I have it, I have a hard time playing any game without it. So if you aren't sensitive to screen tearing now, then you almost do yourself a disservice by using G-sync because it will spoil you.
