RAM:
RAM is a crucial factor in getting the best laptop for gaming. Simply put RAM, or random access memory, refers to the amount of programs you can run on your laptops without running into slow downs. 512MB of ram is optimal for the serious gamers as this will allow for the large memory needed to run graphics that are required for gaming. Basically more RAM equals a better laptop for gaming. Some laptops come with as much as 2GB of RAM! RAM is essential for running video graphics, 3D, and for gaming in general.
Laptops also have what is called dedicated video RAM (VRAM) that is memory, which usually comes with a graphics card (ATI Radeon, NVIDIA GeForce, etc…) and has its own memory in MB which includes 32MB, 64MB, and 128MB. This is a special RAM that is used by the video adapters inside the laptop and only handles graphics and visuals. VRAM is especially helpful for 3D gaming. Today the NVIDIA nForce is considered as one of the best graphics card.
