Bios Magazine posted a review on the MSI P45 Diamond Motherboard

MSI's P45 Diamond is an attractively packaged motherboard (just check out the size of the box!) that performs well for the price. It costs about a third of the price compared to seriously high-end solutions from the like of ASUS and Foxconn, but it's comparable to Intel's X48 and nVidia's 790 chipsets when it comes to everyday usage and gaming. It looks pretty neat (the CircuPipe and the water-cooled Northbridge block in particular), sports an impressive array of onboard features, and the BIOS offers good overclocking and tweaking options. The P45 Diamond isn't the most powerful solution for extreme users (that'll be one based on Intel's imminent X58 chipset and Corei7 processors), but it's a decent all-rounder for the price.
