Ok. I wasn't sure what the actual energy costs would be since the FX-6100 should be a little more efficient. I also just remembered that the Intel board is back from 2008. So I think it has SATA I slots only and has just 2 RAM slots, with 2GB of RAM right now. Whereas my AMD board has 4 RAM slots with 4GB RAM right now and 6 SATA III slots.
