Hardware Canucks posted a review of the ASUS Maximus III Formula LGA1156 Motherboard. Here's a bit:

A new feature that will enthrall everyone (if only briefly) is ROG Connect. By running a USB cable from the Maximus III Formula to a notebook, you can use the RC TweakIt software to make real-time frequency and voltage adjustments remotely. World-class overclockers will this feature useful in order to make on-the-fly changes while a benchmark is actually running. Currently, many of them have been doing this manually on motherboard's like the Rampage II Extreme, that have physical controls that allow the tweaking of system settings. Basically, ROG Connect is almost like the technology that Formula One teams use to tune their cars even while they speeding around a race track.

From a physical standpoint, the Maximus III Formula is built using the same Xtreme Design concept as the P7P55D Deluxe. It has the same Xtreme Phase 16 + 3 phase power design, Stack Cool3+ PCB with two 2oz copper PCB layers, Anti-EMI & Anti-Surge Protection features, and obviously solid state capacitors throughout the board. This is to say that it's a very well-built and designed motherboard. Speaking of design, the usual Republic of Gamers black & red theme is a winner as always, but we wish the PCH cooler was a little more eye-pleasing. The overall layout is excellent, but as demonstrated in the Installation Section, you will want to be wary of CPU coolers larger than the Thermalright Ultra-120 eXtreme, otherwise you will encounter some issues with memory modules with tall heatspreaders.

Once you do have the motherboard installed, you will experience what we discovered is one of the fastest and best overclocking P55 motherboards that we've come across so far. It's not a great deal better than the P7P55D Deluxe in those two areas, but every little bit helps. This is especially true given the fact that the Maximus III Formula really isn't that much more expensive than other high-end P55 motherboards, especially for a Republic of Gamers model. Compared to the P7P55D Deluxe for example, the MIIIF carries a mere $20-30 price premium. That's pretty good in our eyes, especially since you are getting the SupremeFX X-Fi audio module and the intangible pride of RoG ownership.

Pros
- Solid performance.
- Republic of Gamers theme looks good (aside from the slightly bland PCH cooler).
- Excellent layout.
- Nice spacing between the PCI-E slots.
- 2-Way CrossFireX & 2-Way SLI capability.
- Superior manual overclocking capabilities.
- Good failed OC recovery.
- Auto Tuning automatic overclocking works well.
- Perfect voltage regulation & output.
- Good SATA II & USB 2.0 connectivity.
- SupremeFX X-Fi audo card.
- Superb, user-friendly BIOS.
- Comprehensive software suite.
- ROG Connect is like nothing we have seen before.
- Socketed BIOS chip.

Cons
- Voltage read points are too simplistic, need a way to attach voltmeter leads directly to the motherboard.
- Only one BIOS chip, no backup or fail-safe.
- Large CPU coolers + tall memory heatspreaders can cause installation annoyances.
- No IDE/Floppy connector (a non-issue for many nowadays).
- Thermal sensor headers, but no thermal sensor cables.
- A dual-slot graphics card in the 3rd PCI-E x16 slot will overhang the motherboard (unlikely configuration).
