"cheap gaming laptop" - thats just doesnt work , do anything you can to avoid this 3 word combination.
And some simple advice - when buying new machine if the shop doesnt say what exactly graphics card - for example its just said that its 1024MB gfx memory - its bad sign. Ask exactly whats in it, google it and compare with other cards.

integrated cards are crap no matter how new the laptop is - remember that the card is essentialy part of cpu and good gfx cards got higher computing power then cpus..
