Better build quality, better component usage, better feature set, better stability.. These are a few of the parameters which differentiate a higher priced motherboard from its cheaper counterpart.. But quite obviously, its not a linear relationship with price wherein a 3 times higher price tag ensures a motherboard which is 3 times better.. Considering your selection here and comparing with the Asrock 870 Extreme3, we notice an almost 2 times price increase going for the Asrock model.. But again, it is based on a better and more newer chipset, has more features (USB 3.0, SATA 6Gbps, dual pci express x16 card slots etc.) and is also full ATX which brings about a much neater layout design.. So if you look closely, the price difference is all worth it.. But again, if you do not wish to use much of its features, then you are safe with your previous selection.. IMO, you should pay for stuff which you need or know you can use (now or in near future)..
