Best laptop only if you are traveling and want to play games also, but if you are at home i would prefer a Gaming PC than a Gaming LAPTOP.
You can buy a Grate Gaming PC in half price of that laptop.
I Would generally prefer for a assembled Gaming PC.
I assembled my own PC with little knowledge and with the help of GOOGLE, now i dont have to run to computer engineer to repair my pc i can do it at home which also saves a lot of money
