What are the "minimum requirements" for a gaming laptop at the moment to play many games without problems (I have bought a cheap without much thought)?
Would look at the video card and that the screen has Full HD. Higher resolutions take too much power, and the GTX 1060 or RX 580 is perfect for Full HD.
Okay, I have that, what else?
The more memory the better. In addition, it is recommended to install an SSD.
Which game do you want to play
(good) laptops for the Gamign area are quite expensive would recommend a tower PC
16gb is enough for Graka, it should now be over 8Gb Vram
Shooting
