Just like to take the time and warn people about asus's latest bios, whatever you do don't update your bios to 1602 otherwise you'll regret it. What it does is downgrade your processor so that its running at 800mhz (200x4) has a noticeable effect on general system performance as well as gaming. Applies to all x4 users its some kind of bug they introduced when improving compatibility with the latest x6 processors. EZflash won't let you downgrade but there is a solution check the link below for more information.
