Give us a budget to work with. Cheap can be a lot of things.
You want to spend as much as you can realistically on your motherboard. It is the foundation of your entire rig and will largely determine how far you can push your rig, how long you will keep it and how much you can upgrade it. You want as well built a motherboard as possible and cheap boards usually arent. $125 would be as cheap as Id want to go for an overclocking motherboard especially with something as power hungry as an AMD chip.
This Asus 970 board
for $100 would be the cheapest Id recommend with a straight face.
Id rather see you get this Asus 990X Evo
for $130 though. Money well spent.Edited by MacLeod - 12/13/12 at 5:59pm
