This is what Steam considers the "average" gaming PC:
It is less power than a console for sure. 65% of all gamers run games at 1080p,and most dual monitor setups are dual 1080p monitors.
Blizzard Activision makes games,which are mostly cartoony,and made to run reasonably well on a range of hardware.
Also Blizzard Activision for decades was mostly a PC only company. Things like WoW,the Diablo and StarCraft series are PC staples(the first Diablo had a PS port).
The fact that consoles still make a big amount of revenue is not a positive indication of anything. They literally moved into consoles to just get a few extra sales,and it ended up for a few years going the other way which shocked me.
