游戏电脑（或称游戏PC）为游玩运算需求高的电子游戏而设计的个人电脑（PC）。游戏电脑和一般个人电脑非常相似，主要的区别在于配有高性能配件，如高端CPU和一个或多个高端显示卡。游戏电脑往往和配置狂的兴趣部分重叠。然而游戏电脑重在实际游戏性，而高配电脑重在性能最大化，并将游戏作为性能评测标准。二者的不同导致系统花销差别很大。高配电脑唯高端为定义，游戏电脑又可细分为低端、中端和高端。常见的误解是游戏电脑等于昂贵的高配电脑，而实际上显示卡厂商大部分利润源自中低端产品。

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.
