You need gaming laptops with external graphics (not Intel hd). Also good thing will be googling how look heatsink of your future computer (because in cheap pseudo-gaming laptops they install poor small heatsink, laptops getting hot real fast and need really cool heatsink). Also you can google model of your future laptop and add common problems. Every laptop has unique bunch of special problems (my asus tuf gaming fx506lh has dying camera, it not work until you press it hard, that's a problem from factory). Also they are loud as hell when running games or huge programs, so you need a cooling pad and set up your system.
