The processor that carries the Asus VivoBook Pro N552VX it is one of the best there is currently in the market.
More exactly it is the 146 of more than 1,100 processors.
The graphics card, an Nvidia GTX 950M, 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 245 of more than 600 graphic cards.
Oh and be aware, if you're still using jack/mp3 connector, this model DOES NOT have it.
In a nutshell, it will allow you to do what you want and run most games, although not at its maximum quality.
