If you've been playing on console, and tell a PC player that their maxed out 60fps, High resolution and higher graphical settings enabled versions of games were barely noticeable, or that the difference was not huge, they would look at you sideways.

You have to be able to appreciate subtler details. Your getting in effect, remastered versions of games on this hardware without having to pay for a new version of the game.
