Dell XPS 15

Thinking about getting this laptop and was wondering how it would handle games.

16GB RAM Intel i7-7700HQ @2.8GHz GTX 1050 4GB VRAM and intel HD 630

Games like: PUBG, Arma 3, The Witcher 3, Rainbow Six: Siege, Subnautica.

What can I expect and if there is something holding it back, what is?
