A gaming computer (also gaming rig and sometimes called a gaming PC) is a personal computer designed for playing computationally demanding video games. Gaming computers are very similar to conventional PCs, with the main difference being the addition of gaming-oriented components such as one or more high-end video cards. Gaming computers are often associated with enthusiast computing due to an overlap in interests. However, while a gaming PC is built to achieve performance for actual gameplay, enthusiast PCs are built to maximize performance, using games as a benchmark. The difference between the two carries a large discrepancy in the cost of the system. Whereas enthusiast PCs are high-end by definition, gaming PCs can be subdivided into low-end, mid-range, and high-end segments. Contrary to the popular misconception that PC gaming is inextricably tied to high-priced enthusiast computing, video card manufacturers earn the bulk of their revenue from their low-end and mid-range offerings. Because of the large variety of parts that can go into a computer built to play video games, gaming computers are typically custom-made, rather than pre-assembled, either by gaming and hardware enthusiasts or by companies that specialize in producing custom gaming machines. 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. ==History== Historically, gaming computers had several distinct hardware components that set them apart from a typical PC. The push for better graphics began with color fidelity, from display systems such as CGA eventually graduating to VGA, which was adopted for the mass market. Gaming also led the push for the adoption of sound cards, a component that is now commonly integrated onto motherboards. In the 1980s, several non-IBM PC compatible platforms gained a measure of popularity due to advanced graphics and sound capabilities, including the Commodore 64 and Amiga. Video game developers of the time targeted these platforms for their games, though typically they would later port their games to the more common PC and Apple platforms as well. The MSX was also popular in Japan, where it preceded the video game console revolution. Japan also had several other popular gaming computers during the 1980s to early 1990s, including the very popular PC-88 and PC-98 as well as the powerful X68000 and FM Towns.〔http://www.hardcoregaming101.net/JPNcomputers/Japanesecomputers.htm〕 By 1993, PC compatibles were the standard for gaming. ''Computer Gaming World'' stated in January: In September, the magazine replied to a reader asking for "the current '486' desktop dream machine for playing computer games": Falcon Northwest began advertising in ''Computer Gaming World'' in 1993, claiming that the "Falcon MACH series are the first personal computers designed especially for the serious gamer in mind". LAN parties helped to promote the use of network cards and routers. This equipment is now commonly used by non-gamers with broadband Internet access to share the connection with multiple computers in the home. Like sound cards, network adapters are now commonly integrated on motherboards. In modern times, the primary difference between a gaming computer and a comparable mainstream PC is the inclusion of a performance-oriented video card, which hosts a graphics processor and dedicated memory. These are generally a requirement to play modern games on the market. Forays into physics processing have also been made, though with Nvidia's buyout of PhysX〔(【引用サイトリンク】url=http://www.nvidia.com/object/io_1202895129984.html )〕 and Intel's buyout of Havok, plans are that this functionality will be combined with existing CPU or GPU technologies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「gaming computer」の詳細全文を読む スポンサード リンク
