Biostar TForce 550 Motherboard
Though AMD's AM2 socket might be new technology, getting a motherboard that supports AM2 isn't as expensive as you might think. Biostar has released a very capable motherboard that's based on Nvidia's nForce 550 chipset, the Biostar TForce 5500. Though it might be light on features, you can't argue against a stable and well performing $80 motherboard.
