Hello! I am thinking of upgrading my computer for around $600. My specs are an i7 3770 on a gigabyte h61 motherboard, 8gb of ddr3 1333, a Gigabyte GTX 650, an Antec 300 Case, a 500gb 7200 rpm hdd, and a Cooler Master eXtreme Power Plus 500w psu. Should I begin building a new pc so I can overclock. I do mainly gaming at 1080p and record and edit gaming videos. It would be awesome if I could get some help asap, as I am going to Microcenter tomorrow to pick up things.
