However, I remember running it just fine on an old XP machine with a 32bit, single-core pentium III and 2GB of RAM. In addition, this game has been available on smartphones quite some (phone model) generations ago.
Actually, Minecraft is widely derided as being extremely wasteful with resources. And yet yeah, it still runs on my kids' 9-year-old laptop.
Well, aside from the cult of Mac... They spend the same amount of money as gamers, but for bog-standard commodity hardware in a pretty case.
Gamers are willing to pay three times the price for hardware just to get a few percent more performance. I would claim that drives innovation.
I imagine professional workstations for industries such as software development, visual arts, industrial design, film production, music production etc. are large users of high end CPUs.
None of them uses overclocked CPUs (like Intel's K-series) that's fairly standard for high-end gaming
