Wanna take GTA IV read this before

Hey everybody wanna take GTA IV; beware if your graphic card is not more than one gb or does not contains pixel shader 3.0; because then it will not run its a nice game with big map; even they give map and other guidelines with original disc. Its graphic is great with obvious more missions and many more new features.Its graphic makes us feel like we are part of the game.All the things are good except its too high system requirements.
