So I am building a gaming pc. This will be my first time ever building my own or any pc for that matter. http://pcpartpicker.com/p/jtRjvK this is the current setup of the build but I dont know if i should add anything like an optical drive or if I should change anything. My budget is around 1500-1650 and all i plan on doing with this computer is gaming and video editing/recording. I plan on playing the most extreme games at the best quality and frame rate possible. I don't really know how or what overclocking is so i'm not sure on that part. please help.
