Only warning I would give us that this board has no function to allow you to update the bios without a cpu. This means if you buy a very recently released cpu with this board, it may not work until you get your hands on an older cpu that will allow you to flash the bios (or, like me, just take it to a local repair shop who will do it for you) to work with your newer cpu.
Apart from that, during works great. No complaints.
It is a pity I found no information on Amazon but found out on the box itself
