The Gigabyte Z77X-UD5H marks a serious return to the world of high-end motherboards.

Gigabyte has, after all, had a hard time in recent years, being left behind by two of its biggest rivals, Asus and MSI, as they found new, profitable revenue streams.

Things were looking ropey for the Taiwanese motherboard company for a while there; the P67/Z68 debacle was very bad for business and Gigabyte had a host of problems with its X79 boards.

At the start of the year you could maybe find one X79 board from it out in the wild.

Business has picked up though, and more X79 boards have sprung out of the Taipei factory, including the excellent Gigabyte X79-UD3 and following those are a load more Z77 boards.

At last count there where twelve different designs in various form factors.

At the top-end are the two G1.Sniper 3 boards, in ATX and mATX form factors, but sitting just below them, in more sensible black and blue trim (no neon green in sight) is this Gigabyte Z77X-UD5H.

And it's a fantastic board.

We tested all the motherboards here with the same Intel Core i7 3770K processor to test their relative performance across a range of tasks.

Despite running at the same multi-threading Turbo frequency of 3.9GHz (over the stock 3.5GHz) the Gigabyte board has the edge over the Asus P8Z77-V Pro mobo across our entire range of benchmarks; even in the gaming tests where Asus has traditionally held sway.

If you want top performance at the stock settings then you really cannot look past the Gigabyte Z77X-UD5H.
