Add to that the significant overhead a large, bloated, all-purpose OS adds, making a PC matching a console's specs a lot slower than the console. For example, the same hardware that's able to decently power a Chromebook chokes on anything but 'one task' when the OS is replaced with Windows 10.
And, of course, consoles being one, well spec'ed, generally 'frozen' configuration for the life of the console allows developers to optimize their releases to those exact console specs. It's impossible to do that for PCs and therefore the various graphics 'settings'. One example, I got one of my kids an ASUS i5, 8GB RAM, integrated Intel graphics PC. It's not a 'gaming' rig and we didn't expect it to perform well but... 12 fps running X-COM at the lowest settings? That was a surprise.
And, finally, the constant urge to 'keep up'. Soon after you spend a few hundred $$ or the console-killing box, you may end up buying yourself memory upgrades, expesive graphics cards... who knows how many major upgrades cycles you are likely to perfprm over a console's 6-7 years lifecycle. Two? Three?
Oh and... exclusives. I love Bloodborne. There's nothing like it for PCs.
