I am mainly going to be using this computer for gaming. I already have a monitor, keyboard, and mouse. I am probably going to get another stick of memory later on. Are there any better parts I could get without spending much more money? As I said in the title this is going to be my first time building a computer so I don't know what I'm doing. Any comments would help.
