Just as a warning guys...don't expect dual socket A board to be nearly as cheap as Intel GTL+ boards. The reason is simple: Most (read: 4-way and under multiprocessing systems) Intel systems have a SHARED BUS, which most of you know...this also means that adding another CPU doesn't require that many more traces to the chipset. The athlon uses EV6 - a point to point protocol, which requires as many traces on the motherboard for the 2nd CPU to the north bridge as were required for the first CPU to the northbridge. That means more wires, in the same amount of space. Expect > 4 layer PCB boards....possibly > 6 layers. That makes for some expensive mobo's....
