Just concentrate on looking at laptops with "switchable graphics" or laptops with the word "gaming" in the name - - - they have APU graphics for ordinary stuff, plus a discrete AMD or Nvidia graphics card for running games or running software like Photoshop.
However, a custom-built desktop PC is a far better option if you're a keen gamer. Better cooling options, better upgrade options.
Laptops will never be as good for gaming as a suitably-equipped desktop PC on account of the heat factor.
Keeping the inside of an inch-high laptop cool enough to avoid instability or sudden shutdowns when gaming is difficult to say the least.
