I have used Gigabyte P35, H55
I have used Gigabyte P35, H55 and 790X boards and in the past bought into their “value”. For the Sandy Bridge gen, I decided to try Intel boards and have recently built 3 DH67BL boards (1 i3-2100 and 2 i5-2500k). I couldn’t be more pleased with the quality of the boards and utilities.
Gigabyte boards (and many other 3rd parties) use Realtek NICs. They are “OK” for a client, but they really aren’t that great. One of my Gigabyte boards even had Realtek silicon that caused all offloads to be incorrect. When I used an HDHomeRun, I had to buy an Intel NIC to make it work perfectly without incurring network losses.
Both my Gigabyte P35 and 790X boards also had issues with not resuming from sleep properly 100% of the time.
Intel boards have great BIOS features and boot much quicker. As a bonus, the BIOS can be configured to not display a splash such that all you see is the Windows splash when booting which is much more CE-like experience.
The management utilities and driver package are more professional and relevant.
DH67BL or DH67GD would both be good choices for micro-ATX boards.
