SiSoft Sandra's CPU performance benchmark should ideally be identical from motherboard to motherboard. The flat scores here demonstrate that the motherboard manufacturer hasn't affected the performance of the CPU.

The same goes for Sisoft Sandra's memory test: scores here are nicely flat, showing that the connections between the dual-channel DDR3 memory module and the Intel Core i5 processor are performing correctly and at the right speeds.
