Any Help or information on which CPU i should get would be nice im jsut having trouble making up my mind. FYI i am gamer I Play all the Call of duty's all the Command and Conquer Series and Flight Simulators. I've been looking at the charts on here and the i saw that the Phenom II X2 and X3's were scoring higher than the X4 when it came to games.

Thanks
