Our motherboard testing suite has been compiled to subject the system to a variety of different scenarios that help uncover some of the subtle differences in motherboard design.  Normally these differences are driven by the processor and BIOS programming but with the advent of an IMC and PCI Express moving to the CPU we have discovered that raw performance numbers are virtually identical across the systems.  

Our new approach is to look at total system performance and minimize the variances.  The results will tell us how the system responded as a total package and also give us something to use in our comparisons.
