This isn't surprising. Steam is not restricted to "super hardcore PC gamers." Obviously, folks who take hardcore PC gaming seriously are likely to have a better setup than the next console gen (which was also the case for the last 2 generations as well), while people who use Steam frequently but either don't care or can't afford to upgrade their rigs will simply be satisfied using a PC that is good but not great (which was ALSO the case for the last 2 console generations). If you're not into AAA shooters and RPGs (as most gamers are not), you don't need a monster PC. Minecraft and The Sims don't require a terribly complicated setup. While it's interesting to have the survey that confirms it, this is not anything earth-shattering.
