While some hard-core gamers prefer to assemble their own gaming PCs, many seek the convenience and warranty support of a pre-built desktop. At PCMag, we've been testing desktops for 40-plus years, benchmarking gaming models since they rose to prominence in the 1990s. Our analysts and editors draw on collective decades of experience to evaluate gaming desktops, using repeatable, standardized benchmark tests and a range of modern games to assess raw performance.
