none. I recommend not getting xeon cpu's. Unless your doing some real serious editing and rendering. (More than what tv stations do.) I recommend getting I7-4960X if you got the cash it will be able to handle gaming & video editing. Get a real good motherboard too. Like a Asus rampage Extreme. You probably will need 16gb ram (1866 speed) or so. Depending on your budget. Other good cpu's I7-3820, 3930, 3960, 3970, 4820, and 4930.
