If it helps, I myself have a gtx1050 laptop (2gb card, laptop was around 600 euros but on sale), and I’ve seen stable 60 fps on medium/high on Dragon Age Inquisition (stutters a bit, but that’s a CPU bottleneck), 40-50 on medium for The Witcher 3, 60 fps on ultra on Mad Max and TW2 (minus ubersampling of course), 30-50 on No Man’s Sky on low. That’s with a rather weak cpu (I5-7300HQ) and 8gb ram (so basically, the very low-end of “gaming” laptops"). Of course it might not be representative of all laptops in this list but it gives you a pretty good idea of what to expect, I think.
Also, I know its much harder to take into consideration because it requires to read in-depth reviews, but when looking for gaming laptops, I’d try to look for a good heat/noise/performance balance. Many budget gaming laptops have horrendous cooling systems and/or fans sounding like jet engines (for example, the second laptop on the list, the Asus one : I suspect that thing will overheat like crazy, given how thin it is.)
Alson I notice your top pic only has a 256gb SSD, it might be a bit low if you can’t add a second one or an HDD. I’d rather go with an SSD/HDD combo.
