Hardware Secrets posted a review on the Gigabyte Z77-HD4 Motherboard

The Gigabyte Z77-HD4 is an entry-level socket LGA1155 motherboard targeted to the “Ivy Bridge” processors (third-generation Core i3, Core i5, and Core i7 processors). Let’s see what this motherboard has to offer.

The Intel Z77 is an upgraded version of the Z68 chipset with the same basic features (Intel Smart Response Technology and Virtu video switching technology), plus native support to four USB 3.0 ports. It also includes the addition of two new technologies: Smart Connect (allowing the computer to receive emails and refresh webpages while it is in sleep mode) and Rapid Start (faster boot times).

Being an entry-level motherboard, the Z77-HD4 doesn’t support the Virtu Universal MVP technology, which is present on more expensive products and allows you to combine the performance of the integrated graphics processor available in the CPU with the performance of any video card installed.
