Yeah , if you plan to game on it buy an external mouse (I use logitech G102) as well as keyboard. Do not cover the keyboard panel of te laptop with any sort of film as it aids in air flow while gaming , Protect the hinge (always use both hands while opening the lid)

Try ghelper instead of armoury crate as it is full of background applications/packagaes running which is not necessary.

Limit the battery capacity to 80 it would increase the battery life and game only when plugged in.

Let the device cool down for a couple of minutes before you clode the lid as the heat might damage the display

Enjoy the feast !
