I recently purchased an AMD 8320 and an ASUS M5A99fx Mobo to go with it. This is my first computer build so I was wondering what the difference between this processor and an i7 processor. I'm mainly going to use my PC for gaming and FPS's like Arma 3, BF4 and Titanfall. Do you think it is worth dropping some extra $$$$ for an i7 processor or should I stick with what I have?
