Unlike Gigabyte's Z77-based Mini-ITX board, this Z87 variant will have full CPU voltage control.
^ looks like the Z87 ITX will be better but not good, (not heatsinked 4 phase)
All of the Z87 boards in Gigabyte's lineup will come with company's updated DualBIOS firmware interface. Don't let the name fool you: this is full-fledged UEFI implementation. It's also completely new. Gigabyte wasn't happy with the 3D BIOS interface on its Ivy Bridge boards, so it started over from scratch.
The interface is highly configurable; users can adjust not only the color scheme, but also the background image. They can also switch between high- and low-resolution flavors of the UI. The high-res version surrounds the main settings panel with all kinds of system monitoring information, including real-time graphs of certain variables. Only the main panel persists in the low-res mode, an arrangement that keeps navigation consistent across the two versions.
Within the main panel, users can define custom tabs with their favorite settings. Most settings can be manipulated in multiple ways: there are sliders to drag, lists of options to scroll through, and fields that allow values to be keyed in directly. The interface is responsive when navigating with the keyboard, but the mouse tracking feels a little laggy. It's not as bad as some of the early UEFIs we encountered on Sandy Bridge boards, but there's definitely room for improvement.
In addition to revamping its motherboard firmware, Gigabyte has overhauled the accompanying Windows software. This clean-sheet redesign has been in development for about a year, and it shows. The interface is streamlined, consistent, and reasonably responsive. Unfortunately, it's also modeled after Windows 8 tiles, which means some elements are unnecessarily large. At least the software runs on the desktop rather than in Win8's Modern UI.
The EasyTune tweaking component offers pre-baked profiles for newbies and manual controls for seasoned enthusiasts. No surprises there. The fan controls are similarly segmented, but there are a few new twists. Gigabyte has incorporated a calibration routine that probes the range of rotational speeds supported by each fan connected to the board.There's more granularity in the adjustable fan curves, and temperature-based speed control can be applied to a greater number of onboard headers.
