Not sure if it can be beat but it can be matched.
I tested effeciency of all the boards......my prediction was either CH III or MSI, msi better in GT3 than all other boards, CH III was better than all other boards in GT1 and 2.
fwiw you can take my m4a79_t results with a grain of salt, all my boards were damaged goods ;)
