consoles are not upgradable so over the years a console will be absolote while your pc will have been upgraded to play all the latest games.
Game play wise, there are certain games i wouldnt buy on a console, like GTA and FPS games, as playing these games with controller is a load of shit compared to a mouse and keyboard. Yes i know you can get mice and keyboards for your console, but they dont come as standard do they, same as youo can get controllers for a pc but they never come as standard.
Graphics, i cant tell the difference

all looks the same to me.
