Too Long; Didn't Read
PC Gamers commonly find a lot of "gaming" options for regular items such as mice and computers. Typically, peripherals benefit most from this sort of branding, as mice and keyboards sometimes have custom features tailored towards specific games. The branding doesn't matter as much for computer components such as motherboards, but items designed with that branding are very well-suited towards gaming thanks to their high performance. Accessories benefit from a "gamer" label the least - very few Mouse Pads have features that justify such branding, and gaming chairs are largely uncomfortable - at least in this writer's experience.
