pc people aren't all about graphics, just check the steam games library of vgc members, most of their games are bad looking games, they own them exactly for the reasons you mentioned. the game i play most on pc atm is legend of grimrock and surely not for the graphics.
but still, nothing wrong with it to play the games you own with the highest possible settings with as many fps as possible because that just increases the quality of the game you like even more. same with mods, skyrim is great on console but it's even better with mods, smoother frame rate and whatever else.
