BIOS updates come out for motherboards all the time and usually aren't talked about much on review sites since they usually fix minor bugs or update the board with the latest CPU information. Nothing too impressive and nothing worth writing an article about. Earlier this week Gigabyte released beta BIOS F7B for their GA-890GPA-UD3H motherboard and we didn't bother dedicating any time to it until this morning when we noted that the description for this board said that the BIOS update would improve power consumption.  What in the world could this be?  It's not every day you see a BIOS update being released that improves the efficiency of the board!
