Yeah. Right now I'm using a 4 year old Alienware laptop that just isn't cutting it for the new games, PUBG on lowest graphics and destiny on lowest graphics and still frame issues all the time
The one that costs 1680 is the on you should go for. It has a 1080. The third one is 80 bucks cheaper for a 1070 ti. The 1080 is worth the extra 80 if youre already paying 1500+
