According to report of Cyberland, the reason for the high system requirements is the fact that the GTA V PC would have higher resolution textures, better models and an improved shading system that won't even appear on the PS4 and Xbox One version of the game.
GTA V will be released on PC, Xbox One and PS4 on Fall 2014.
