Dolby Home Theater® - Enjoy a Rich Home Theater Surround Sound Experience.
Dolby Home Theater places listeners in the middle of the action, giving their PCs a powerful set of tools to deliver a cinema-style experience in vivid surround sound.
- Delivers vivid surround sound for music, movies, and games, using two to eight speakers or any set of headphones.
- Designed to automatically deliver the best possible listening experience.
Dynamic Energy Saver Advanced.
GIGABYTE Dynamic Energy Saver Advanced provides better energy saving capabilities and enhanced system performance. GIGABYTE Dynamic Energy Saver Advanced is the world's only motherboard energy saving technology with hardware-based Dynamic 6-Gear Switching. With support for VRD 11.1, GIGABYTE’s DES Advanced allows the motherboard to switch to 1 Gear phase switching during idle, allowing for a dramatic increase in power savings.
GIGABYTE has also retooled Dynamic Energy Saver to allow overclockers to experience the benefits of multi-gear power phase switching while overclocking, providing ultra stable, ultra smooth overclocking performance.
Ultra Durable 2 -Designed with Top Quality Highly Efficient Components.
- Ultra Cooling - Low RDS(on) MOSFET Design.
Low RDS(on) MOSFETs specially designed to produce lower switching resistance for faster electric current charging and discharging.
- Low Power Loss - Ferrite Core Choke Design.
Ferrite core chokes comprised of a compound of iron oxide and other metal elements whose properties hold energy much longer than common iron core at high frequency.
- Longer Life - All-Solid Capacitor Design.
Solid capacitors contain a solid organic polymer, while electrolytic capacitors use a common liquid electrolyte, hence, the terms solid capacitor versus electrolytic capacitors.
Ultra TPM - Industry’s highest level of data Security via onboard TPM.
- Maximum level of data protection with 2048 bit encryption.
- Security, manageability and flexibility that surpasses software-based encryption.
- Portable User Key to protect data when away from your system.
- Additional backup of user key in BIOS in case of misplaced key.
High Velocity 2X Bandwidth Boost.
The Dual LAN with Teaming functionality enabled allows 2 single connections to act as 1 single connection for 2x Bandwidth, improving overall throughput.
Prevents network downtime by transferring the workload from a failed port to a working port.
Receive Side Scaling balances the network traffic load evenly between 2 CPU cores in order to improve performance.
Adjusts power consumption automatically according to your LAN cable lengths, up to 10% power savings.
Hardware Overvoltage Control ICs.
Hardware Overvoltage Control ICs which provide more voltage control options than before for the CPU North Bridge and memory. The overvoltage controllers also provide hardware linear real-time voltage control. In addition, Hardware Overvoltage Controller ICs also allow for much finer voltage control, allowing power users to adjust voltage in as little increments as 20mV for better overclocking performance.
EasyTune6.
GIGABYTE has completely redesigned EasyTune6 from the ground up to make it easier than ever to manage and monitor your hardware resources as well as tweak your system settings in order to achieve maximum system performance. Whether you are an overclocking enthusiast, or a computer novice, EasyTune6 provides the tools you need to quickly and effortlessly fine tune your system.
Smart Backup- Plug & Play Hardware RAID.
GIGABYTE’s Smart Backup allows users to connect up to 4 Serial ATA devices for effortless RAID data protection. Dual onboard RAID controller chips automatically configure RAID setup without user intervention, making it easier than ever for users to enjoy enhanced data transfer performance, low CPU utilization, real-time backup on-the-fly and protection against HDD failure.
DualBIOS™ - Patented Dual Hardware BIOS Protection.
DualBIOS™ is a GIGABYTE patented technology that automatically recovers BIOS data when main BIOS has crashed or failed. Featuring 2 physical BIOS ROMs integrated onboard, GIGABYTE DualBIOS™ allows quick and seamless recovery from BIOS damage or failure due to viruses or improper BIOS updating.
Onboard Diagnostic LEDs - Hardware Troubleshoot at a Glance.
7 Onboard LEDs controlled by the system BIOS indicate if a malfunction is occurring, allowing users to directly see where the problem is occurring, so they can quickly take question.
Onboard ACPI LEDs - Power Status Indicators to avoid improper hardware removal.

Theres just about everything on here that an enthusiast may desire... 
layout... 
Expensive (but worth it if you need all of the features), Wish there was an option to disable the onboard LEDs in the BIOS, Not enough temperature and voltages readouts/sensors, Some SATA ports blocked when a graphics cards is installed in the second PCIE...
