While the GPU, CPU and screen are the holy trinity of gaming, you should also check our reviews to see what else the laptops offer.  The keyboard is probably the next most important element – assuming you will plug in a gaming mouse rather than using the trackpad – and they are not all created equal.  Cheap budget laptops have a couple of potential advantages over top-end models due to their thicker chassis. The chunkier design means more space for various ports, meaning connectivity is often better than more expensive options.  It also means more space for a battery and, combined with lower power components and Full HD displays, could offer longer battery life. Check our reviews to see how many hours they can last away from mains power.
