A gaming computer (also called a gaming PC) is a personal computer designed specifically for playing graphics and system intensive video games. Gaming computers are essentially conventional PCs, with the addition of gaming-oriented components such as one or more high-end graphics cards, more RAM and faster procesors to accommodate the increased requirements for processing power.
Because of the large variety of parts that can go into a computer built to play video games, gaming computers are sometimes custom-made, rather than pre-assembled. This can be either by gaming and hardware enthusiasts or by companies that specialize in producing custom gaming machines such as Alient Ware. In order to generate interest, gaming computer manufacturers that sell complete systems often produce boutique models, allowing them to compete on aesthetic design in addition to the hardware inside with extravagent cases manufactured by companies such as Antec.
