Newegg only sell one AM2 motherboard and it isn't compatible with that old CPU: http://www.asrock.com/mb/NVIDIA/N68C-GS4%20FX/?cat=CPU Why would you spend money on such an old CPU? Look for a compatible motherboard on eBay, but unfortunately CPUs last longer than motherboards and that often makes old ones expensive.
