SummarizingThe processor that carries the Asus X751NV it is not highly recommended. The experience you will have will not be the most fluid in many of the cases and the volume of tasks you can do at the same time will be quite limited.
If you are also one of those who use antiviruses because you are not careful with what you download, it is likely that in a short time use it become hell.
More exactly it is the 1404 of more than 1,100 processors.
The graphics card, an Nvidia 920MX, 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 383 of more than 600 graphic cards.
The amount of RAM is quite short, 4GB were top a few years ago, but today... The operating system itself can eat half that amount.
Oh and be aware, if you're still using jack/mp3 connector, this model DOES NOT have it.
It has a huge screen.
In a nutshell, it will allow you to do what you want and run most games, although not at its maximum quality. it will serve you for office tasks such as writing or surfing the internet and little else.
