TweakTown posted a review on the ASUS P7P55D-E Pro (P55 Express) Motherboard

After spending some time with the H5x series and the Clarkdale, we decided to head back and look at the newly revised “E” version of ASUS’ P7P55D series. These boards have been worked over to include both SATA 3.0 and SuperSpeed USB, all for a relatively low $189.99 over at Newegg. With the P55’s limited PCIe lanes, including these new technologies has required the use of a bridge chip to allow for proper PCIe bandwidth.

The P7P55D-E Pro also includes ASUS’ 16-Hybrid Phase (12+2 with T.Probe) which allows for real time balancing of power and heat generation. ASUS rounds out the P7P55D-E Pro with Auto-Tuning, Express Gate OS (a linux based OS for quick use) and Turbo EVO.
