Gigabyte Z77X-UD3H Motherboard Review @ RWLabs
 

The Intel Z77 Express chipset is the evolution of the Z68 Express chipset, as instead of doing an overhaul of the platform Intel instead just added native support for technologies such as USB 3.0, SATA 6Gb/s and PCIe x16 Gen 3.0. These features are a huge step in the right direction, but since they are integrated into all Z77 chipset it is still up to the motherboard manufacture to add the magic and make their product stand out from other motherboards sporting similar features.
