Summary: Worked well for about 2 months. Now SATA ports and NIC port do not work properly or at all. Swapped in a different mobo keeping ALL other HW the same and everything works fine! My conclusion: this mobo has failed!
Summary: Buyer beware -- this is a full sized board, not mATX sized board as pictured. I reported this to Amazon picture feedback as an incorrect image, but in their infinite wisdom they "determined that no change needs to be made to the product image." Hmmm... The picture as of 5/24/11 (if you zoom in) shows a GA-H57M-USB3 mATX-sized motherboard, not the GA-H55-USB3 full-ATX-sized motherboard that you will receive if you order this item.
Worked fine, unlike the new Intel motherboard it replaced

Summary: My son wanted a custom built machine, so we started by ordering an ATX case ( Cooler Master RC-600-KKN1-GP Gladiator 600 Mid Tower ATX Case with 140mm Fan (Black) ), an i7 CPU, and an Intel DP55KG Extreme Series Desktop Motherboard (P55 ATX Core i7 Core i5 LGA1156) . The Intel motherboard refused to accept any memory we put in it (three different varieties, all meeting the proper specs), so we could never get it to boot.
Summary: I've had this MB in use for over 6 months with no problems. Easy to install and set up the included software makes the whole process a snap. I would buy another one if I was building a second computer. And it's pretty.
Summary: I don't always go for Gigabyte when I build or recommend, but this one had all the requirements, and I was willing to try something new. I liked it, I really did. All except the blindingly blue color...but, that's neither here nor there. It's hard for motherboard manufacturers to differentiate their products in today's processor climate, especially with Intel publishing specs for onboard video in the H55, but Gigabyte adds in some USB 3.0 action, which, while I didn't...
Summary: Gigabyte makes a good motherboard. I've had mb's from Gigabyte in the past and I will continue to buy Gigabyte mb's. The documentation is pretty good and tries to give a brief examination of all features. Build quality is great on the H55-USB3. Only minor (very minor) complaint was where they put the connector for the floppy drive. I happen to have a floppy drive and the cable must stretch to the opposite corner of the board.
