These are the ONLY motherboards I would consider using with that CPU. Others might show that CPU on the CPU support list, but it doesn't mean that they will work well or that you won't have thermal or VRM isssues.
(Be sure to check when looking for a motherboard that any of the models shown below are either 990fx, 990 or 970 chipsets. A Z170 Extreme6 for example, is not going to work with your FX processor, so, in this example, you want to look for the 990/990fx Extreme6.)
