HP ZBook 17 G6 Mobile Workstation - Customizable
The graphics card, an Nvidia Quadro 3000M, is nowadays quite passable. We could say that in the middle range. You will be able to watch Youtube / Netflix/etc... in good quality (1080p or more) and you will be able to play comfortably the majority of games.
More exactly it is the 336 of more than 600 graphic cards.
Oh and be aware, if you're still using jack/mp3 connector, this model DOES NOT have it.
It's incredibly light, so if you're looking for mobility it's perfect for you.
It has a huge screen.
