Hi, I've just built a new pc and i bought a new motherboard called Gigabyte 78LMT-USB3. It works with an amd 8core processor. But the question is: How can i update my bios and also i saw some GA78LMT-USB3 and mine is 78LMT-USB3. I don't know if there is any difference or GA is only for Gigabyte. I've also saw about rev 4.1 or 4.2, i don't remember well about it but idk what does that mean. I think i need some help hehe. ^^'
