Will this build work for a gaming computer?

Why are you pairing such an expensive motherboard with a relatively cheap PSU?

Have a look at socket 970 boards like the Asrock 970 Performance or the Gigabyte GA-970A-UD3P they have good overclocking potential but cost less than $100

 


As long as you have a fan or two in the front pulling air in and the rear and top pulling out you should be fine. Make sure you do nice cable management as you can only benefit from better airflow and a nicer looking rig.
