What is difference between ASUS A8V-VM and a ASUS A8N-VM
motherboard? Does anyone know what the difference is between these motherboards? I have seen that one has 4xDIMM slots and the other has 2xDIMM, but what other differences are there. Have been sold one on ebay and the description was for the other one. Want to check I have not been ripped off. Also which one is best etc.
