@shaka999: You currently don't have a aftermarket cooler in your build to use the overclocking capability of your CPU.
I know a lot of people think overclocking is the shit, but it's really a useless premium for what you are going to be doing (which is gaming). Save $90 or more dollars and put that towards a better GPU or SSD. A better GPU or SSD will give you a far better performance increase then the measly 2 or 4 FPS you might get in a game by overclocking a CPU.
I put together this system, which I think gets you a better deal for the same price. The big difference being that you'll get a 120GB SSD for you OS and a few games. You put about 150 more watts to your PSU than the GPU's recommended power requirement. That requirement is given for people that buy off-band PSUs. The 500W bronze certified PSU in this new build is more than enough. A lot of first time builders spend more on their PSU than needed. I also got cheaper RAM, since you don't really need to spend more money for red RAM whose extra speed really isn't helpful to your needs. DDR3-1600 is quick enough for what you need.
Imo overclocking,while "cool", is a waste. You should really check out r/buildapc on Reddit and ask for their advice too.
