High Quality Content by WIKIPEDIA articles! A gaming computer (also gaming PC and sometimes called a gaming rig) is a personal computer that is capable of playing computationally demanding video games. Gaming computers are very similar to conventional PCs, with the main difference being the addition of performance-oriented components such as a high-end CPU and one or more 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.
