HardOCP posted a review on the MSI Z77A-GD55 LGA 1155 Motherboard

The MSI Z77A-GD55 is a Z77 Express chipset based motherboard designed for socket LGA1155 processors. The feature set for the motherboard as well as its model number places it in the low to midrange motherboard market. Despite being basic, it still has many features to offer. The motherboard has several MSI specific features to offer such as MSI's Military Class III design specifications, Click BIOS II, and OC Genie. Naturally a lot of that is marketing speak for features others have as well, such as UEFI and automatic overclocking, but MSI does have unique implementations of these features.

Among the more technical features of the motherboard are DrMOS II MOSFETs, Hi-c Caps, solid ferrite core chokes, solid electrolytic capacitors, and active phase switching. Additional features provided by the chipset are 4 SATA II 3Gb/s ports, 2 SATA III 6Gb/s ports, PCI-Express 3.0 and 2.0 support, SLI / CrossFireX support, and support for USB 3.0 devices.
