Every month Valve conducts in-depth surveys to determine the most popular hardware and software solutions used by Steam gamers and compares them on a month-by-month basis. Last month's survey report reveals that most gamers are using stock hardware rather than high-performance rigs.
According to July 2015's hardware survey, only 34% of Steam users play at 1920x1080 resolution, with 26% running games at the laptop standard resolution of 1366x768. Out of the gamers that opt in for multi-display gaming, a full ~29% of these users run at 3840 x 1080 resolution.
When it comes to CPU's ~48% of Steam users run dual-core CPU's, with quad-core CPU's close behind at ~45%. The bulk of CPU clock speeds are between 2.3 GHz and 2.6Ghz, but the 3.3-3.69Ghz clock bracket is on the rise accounting for approximately ~16% of users. Intel CPU's predictably dominate with an inclusion rate of 75% versus AMD APU's at just a quarter of users.
