GIGABYTE 3D Power (patent pending)
GIGABYTE X79 series motherboards are the first to take advantage of the exclusive GIGABYTE 3D Power, an all new hardware and software-based Digital Power Engine for both the PWM and Memory that delivers unprecedented power delivery control.

All New Digital Power Control for the CPU and Memory
Utilizing a brand new Digital PWM controller, GIGABYTE's 3D Power features precise Auto Voltage Compensation to deliver a steady flow of power to the CPU and memory no matter the loading. This all new, all digital power system provides enthusiast users with exceptional control over the overclocking potential of their GIGABYTE X79 motherboard. GIGABYTE is the first in the industry to utilize digital memory controllers for not only the Memory, but VTT and VSA, for real-time monitoring and adjusting. Digital memory control allows users to monitor and record DDR power and current in real-time while gaming, overclocking or at idle. Users can also set OVP (Over Voltage Protection) to safeguard your memory, adjust memory Load-line Calibration to fix memory vdrooping for a quicker response time and adjust memory PWM frequency on-the-fly.

GIGABYTE 3D Power(patent pending) Utility
Users can now enjoy a fully interactive 3D utility that facilitates adjustment of the 3 dimensions that control the power delivery to your CPU and Memory: Voltage, Phase and Frequency. These parameters are crucial to how the digital PWM supplies power to critical areas of the motherboard and can help users quickly obtain the highest, most stable overclock.

3D Power: Voltage Control
Voltage parameters can be modified within 3D Power, including load line calibration the of CPU. By adjusting load line calibration, Vdrooping can be avoided, maintaining optimal voltages levels despite increasing current levels. OVP (over voltage protection) can also be adjusted to change default protection range of the CPU, memory controller, VTT and system memory.

3D Power: Phase Control
Users can calibrate OCP (Over Current Protection) for the CPU, integrated memory controller and system memory power levels. This allows the Phase control to deliver even more power to the system when needed.

3D Power: Frequency Control
GIGABYTE's digital PWM allows for adjustable frequency control via the International Rectifier (IR3567) PWM controller. 3D Power frequency control allows users to change the PWM controller frequency so that the CPU VRM can adjust power delivery speeds more quickly. Users can also adjust the PWM spectrum or maximum and minimum overall frequencies

GIGABYTE 3D BIOS(patent pending)
The revolutionary GIGABYTE 3D BIOS application is based on our new GIGABYTE UEFI DualBIOSTM technology and is available to consumers in two new exclusive modes of interaction never before seen in a BIOS environment. GIGABYTE has re-drawn the traditional BIOS experience providing mainstream and enthusiast users with a choice of unique and powerful graphical interfaces.

UEFI DualBIOSTM Technology
At the heart of this exciting 3D BIOS technology is a pair of 8MB physical BIOS ROMs containing GIGABYTE's exclusive in-house designed UEFI BIOS technology. With a superior graphical interface capable of 32-bit color imaging and fluid user-friendly mouse navigation, UEFI DualBIOSTM makes BIOS configuration a new and exciting experience for novice and experienced users alike. UEFI BIOS also brings native support for large hard drives on 64-bit operating systems.

3D Mode
Designed to provide an extremely streamlined and user-friendly BIOS environment, GIGABYTE's exclusive 3D mode offers a fully interactive and illustrative GUI that allows users to easily and intuitively make key adjustments to the UEFI BIOS settings for optimum performance. 3D Mode allows novice or casual users to more clearly understand the areas of the motherboard that are being affected through the BIOS settings, gaining a clearer understanding of the BIOS functionality.

Advanced Mode
Advanced mode provides a more comprehensive UEFI BIOS environment that is designed specifically for overclockers and power users who want maximum control over their PC's hardware. GIGABTYE's signature M.I.T. tuning technology can be found alongside fully configurable parameters for GIGABTE's all new digital 3D Power engine. In short, advanced mode combines the signature GIGABYTE BIOS expertise you’ve come to expect, wrapped a slick, new and optimized graphical UEFI interface.

GIGABYTE Bluetooth 4.0 and WiFi Card

With 2 kinds data transfer mode, GIGABYTE Bluetooth 4.0 and WiFi Card providing spec 300 Mbps transfer rates, 802.11n supports the latest WiFi specifications for better signal coverage, and featuring the newest Bluetooth 4.0, you will not suffer from signal loss like before.

Booted first time. Good documentation. Loaded with i7-3930K cpu, 32GB DDR3-1600MHz, SSD, & 2TBx2 in RAID0. Nice to have 6 SATA3 ports, and front & back 1394 & USB3.0. Using all 4 fan headers too. Easy to use and upgrade BIOS. Just using $10 gfx until PCIe3.0 cards arrive. Easy to install & attach everything!

I switched to Gigabyte motherboards about 2-3 years ago when (in my estimation), Intel seemed to be having a lot of issues with its motherboards. I have 2 EP45s and a P67 (all Gigabyte) that have been rock solid. I was a little nervous about the purchase as I, too had read the Newegg reviews. It seemed as though I would have to spend $400+ to get a solid X79 chipset. I crossed my fingers and got the Gigabyte X79 w/8 dimm slots ($269.99 + free ship + no tax). I also wanted a lot of onboard SATA ports as I was going to run a 4x500GB RAID 0 with a 2x60GB SSD RAID 0 for my OS. I will admit that I'm not crazy about the cheaper onboard Marvell chips, but all I use Marvell for are my dvd/bluray drives. So far, the board has been rock solid with 64 GB DDR3-1600 G.SKILL and the Intel 3930K chip with an Intel water CPU cooling system. Its all in a HAF932 case with a fan pretty much in any place that has the mounting holes. I put my 4 WD drives in a Cooler Master 4-in-3 and my 2 Intel 520 SSD in the drive bays. All of the disks share 2 cooling fans (1 in the case and 1 in the 4-in-3). I dedicate 48GB of my memory to VMWare because I usually run several VMs. So far, I haven't been able to really tax the system - it handles pretty much anything I throw at it. I develop software and work a lot from my home office, so I wanted a system that would last 4 or 5 years before it started getting bogged down. So far, so good - usually if the hardware lasts 6 months with no issues, it will then last for several more years. Gigabyte rocks! Also, I can get TRIM passed to my SSDs in RAID 0 now because Intel just started supporting it on series 7 chipsets.

Windows experience cpu 7.8, mem 7.9, both graphics 7.8, Hard disk 7.9 for 7.8 overall

This motherboard is a beast! So much RAM, PCIe x16x2 and x8, LGA 2011. My computer registers as a 7.7 on the windows Experience index. Graphics card (EVGA 560 Ti) is 7.8, RAM (16GB Corsair Vengeance) is 7.9, and the Processor is an i7 3820 which is the bottleneck at 7.7. I am not complaining about that though. It's wicked fast.

The only complaint I have is finding a cooler for it... With my extremely tall Corsair Vengeance RAM, I had to get Corsair's H80, and that still touches the RAM closest to the radiator..
Overall, I wish I had gotten the Corsair Vengeance LP RAM, but I'm happy as is.

Highly recommend.

been running this every day since purchased with a Intel Core i7 3820, 32 Gigs of Corsair 1600 MHZ, a SanDisk Extreme SSD 120 GB SATA, 1 TB WD Black hard drive, Corsair Hydro Series High Performance Liquid CPU Cooler H60, and 1 Panasonic bluray burner. all purchased here at Amazon. Running WIN 8.1 Pro 64 bit.
This board is a little tricky when installing the SSD and setting up the rest of your SATA drive hardware. So don't freak out if your Blu ray or DVD software doesn't recognize all of the burning features of your DVD-CD BLU-ray drives. It's not the motherboard, it's not the drive, it's not the software..... it's the GA-79's BIOS settings.
Just read up on the instructions for the BIOS settings and placement of the SATA cables and you'll be fine.

Cheapest LGA2011 Workstation board. This is not only a gaming board but a workstation capable board. It has the Intel C606 board which gives it ECC memory support, SAS, and Intel workstation grade NIC. A similar board like this by Tyan or SuperMicro is over $400 without all these extra features such as SLI, WIFI, BT, and Firewire.

I used this board to build a Hackintosh with a 3930K overclocked to 4.2GHZ and my Geekscore 64bit benchmarks hit 23k that surpasses the 6 core Apple Macpro 2013 model. Had I boosted clocks to 4.5ghz I should hit 25k easily.

The board is huge and has a ton of room to expand. Did I mention this makes a really kick ass Vmware ESX box?
