for the small difference in price id jump to the a8 5600k personally. but that aside.
whilst im not certain which boards will have outa the box support. running the latest bios on ur hardware is a habit you should get into, no better place to learn than on a secondary pc.
you will find it is alot easier than it sounds. generally all u will need is a flash drive, and manufacturer will provide u with step by step instructions on how to carry it out correctly.
take 5 mins, matter of putting a flash drive in upon boot, hitting a few buttons and doneski.
