Do you find Gsync necessary for gaming?

I have to buy a gaming laptop with an Nvidia graphics card! A second monitor should have Gsync in my opinion… But is it really only worth it for gaming? Do you notice a difference as if you didn't have a Gsync?

It's nice to have, but not necessary

Yeah, I bought one with G-Sync back then and it's nice. But as with everything, as long as you haven't had it you don't miss it, once you have it you don't want it without it.
