A gaming computer (also gaming PC and gaming machine) is a personal computer that is capable of playing modern hardcore video games. Gaming computers are very similar to conventional PCs, with the main difference being the addition of a performance-oriented video card and larger amounts of RAM. Gaming computers are often associated with enthusiast computing due to overlap in interests. However, while a gaming PC is built to achieve optimum performance for actual gameplay, enthusiast PCs are built to compete against each other for the highest possible performance figures, using games as a benchmark. The difference in optimum performance and maximum performance carries with it 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[citation needed].
Such computers are typically custom-made rather than pre-assembled. However, some computer companies offer gaming computers in addition to their regular product lines. Some companies, such as Alienware, StormFreeze Technology, CyberPowerPC, Performance Personal Computers, and OriginPC specialize in producing custom gaming machines.
Computer cases for gaming computers tend to be flashier; cases with clear sides are common, to reveal the internal components which may be adorned with LEDs. In addition to aesthetics, gaming cases are also designed for function; the case must be able to provide cooling for high-end components, and have room for expansion and customizationHardware
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, most notably the Commodore 64 and Amiga. Computer 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 sometimes Apple platforms as well. The MSX was also popular in Japan, where it preceded the video game console revolution.
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 typical PC is the inclusion of a performance-oriented video card, which hosts a graphics processor. Some motherboards support up to four video cards through SLI or Crossfire. However, such configurations are typically regarded as a curiosity for enthusiasts rather than a useful alternative to single-card upgrade cycles.
Forays into physics processing have also been made, though with Nvidia's buyout of PhysX and Intel's buyout of Havok, plans are that this functionality will be combined with existing CPU or GPU technologies.
[edit]Prebuilt Gaming PC
While many "hardcore" gamers build their gaming PCs themselves, some choose to go with prebuilt or custom-built gaming PCs. These PCs can often be more expensive than building one's own, with higher premiums attached to high-end brands with varying levels of customer service. Different companies offer varying degrees of customization, some almost as much as building it oneself. There are however, drawbacks to building one's own computer. Assembling a computer means being personally responsible for any problems that may arise, both during the assembly phase, and after it's in regular use. Instead of using a single technical support hotline to cover your entire system, often own will have to deal with individual component manufactures. Due to the wide inconsistencies in after purchase support from component manufactures, trying to get support can be a daunting task for even the most patient of persons. Customer support is a major reason why even extreme gaming enthusiasts may look to a system integrator for their custom PC builds. There are many positive aspects in choosing to build one's own system, such as no longer being tied to specific configurations. Pricing on individual components is often better, and thus saves quite a lot of money on a comparable pre-built system.
