Notes
We've historically had a large number of benchmarks detailing performance between chipsets. Due to the levels of integration in the processor practically all modern motherboards benchmark at the same levels, give or take a per cent or two, so 15 graphs showing near-identical performance isn't what you (or we) want to see.
We're running nine benchmarks - three CPU, three gaming, three storage - to see if the boards perform at the expected levels. This is more of a sanity check than anything else. Of rather more importance is how well the boards are able to overclock the CPU and Corsair DDR4 memory.
