I’ll agree that “gaming equipment” is a bit vague, since that can mean anything from full hardware to tiny accessories. For me, though, both my gaming hardware and my peripherals follow the same pattern; I use them until they physically can’t keep going anymore.
Most of what I use is wired, so I don’t really deal with battery issues or wear from charging cycles. The only thing I replace with any regularity is my mouse, since it’s the only wireless device in my setup, and eventually the battery or switches start to go. Everything else tends to last me a long time.
