I have an FX-6300 running on a Gigabyte GA-970A-UD3P and I have no problems whatsoever. I got the motherboard for only $70 and no bottlenecking or anything. Motherboards don't usually determine how good your rig will perform in a game. It mostly depends on what GPU. What games will you be playing? I have an AMD Radeon R9 270X that runs Battlefield 4 Ultra at smooth framerates with my FX-6300. It was a really cheap rig, yet pretty powerful.
