For proper functioning of GPU, it is essential to have VRAM of their own. This is beneficial in storing different frames, textures and other required properties for getting frames for the monitor. Finding out how much you require may be tricky. Hence, it is better to go for a laptop with as much VRAM as possible. You can buy a laptop with 3-4 VRAM. If you have reduced budget, you can opt for 2 GB VRAM. You, however, need to ensure that the resolution of the gaming laptop is 1080P.
Still, unless you're attempting to become a professional gamer or get ranked globally in a particular popular title, a 60Hz screen will suffice. Nearly all gamers are still "stuck" with 60Hz displays, after all. High-refresh panels aren't common in budget machines, but they are worth knowing about, as we expect them to trickle down into under-$1,000 machines soon.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping.
