I bought the mboard brand new, what I want to know is will a AMD FX-6300 run on the mboard straight out of the box? After I ordered and payed for the parts I read something about needing to update the bios if it previously had a cpu installed I'm kinda confused how does a mboard need a update if it's new and say for instance you don't have a older cpu to flash it? Box for mboard says Am3+ ready
