Summary: Summing it all up is pretty easy. The P7P55D-E PRO is a definite winner in our books, with only a few points that hold it back. The power savings is something that impressed hugely, as this was not expected at all, and the P7P55D-E PRO's ability to hang with the Gene in clocks, albeit with slightly less performance, makes this board an option that everyone should seriously consider, whether as a daily driver, or as the foundation for a hardcore overclocking machine.
Pros: Fully featured with SATA 6 Gbps and USB 3.0, Properly built to maintain high overclocks through long-term daily usage, Modest pricing, Lowered CPU power draw via T.Probe, reducing load power consumption by almost a third, Excellent XMP support, even with fully populated memory slots, Easy to use socketed BIOS with loads of options
Cons: High "Auto" voltage settings, Lack of software memory timing control, Modest overclocking results, affected by power-saving PWM, "Hybrid" nature of the board leads to many clocking features, most of which aren't highlighted on packaging
