This board doesn't have the newer sata 6.0 or usb 3.0. Looks like one of the newegg reviewers mistakingly listed these features. Can't predict if your board will post with your cpu, but newegg usually carries newer boards, so it may work fine. If it does, I wouldn't flash the bios until you try the old one first. Some newer bios updates don't overclock as well. Try overclocking first before deciding on the bios flash.
Sata 6.0 and USB 3.0 is not that important for me. And I'm replacing my old motherboard and CPU so if it doesn't post I'm pretty much screwed and all money will go to waste, therefore I need to make sure that the mobo I buy supports c3 out of the box
