I agree with previous poster, there's no such thing as a "cheap" gaming laptop - - cheap laptops are only for general & office use.
If you want a high-performance laptop that can handle games, you must be prepared to pay more otherwise you are going to be disappointed.
The best type of computer for gaming is a desktop model with a dedicated, high-performance AMD or Nvidia graphics card, and a decent case with adequate cooling to avoid overheating (something which laptops struggle with because of their lack of space inside).
