I've had my Intel DZ77GA-70K motherboard installed and running for almost 3 months now. Here are my system specs:

- Intel i7-3770k CPU (Retail, boxed, used Arctic Silver 5 thermal compound)
- Intel RTS2011 Liquid Cooling CPU cooler with 120mm fan
- Intel DZ77GA-70K motherboard running 0064 BIOS (flashed to 0064 on 3/15/2013)
- Crucial 32GB DDR3 RAM (Ballistix Sport)
- Intel 120GB Model 330 SSD (SATA III)
- PNY GTX 650 video card
- WD 3TB Red hard drive (SATA III)
- Corsair 650D case with 3 x 200mm fans
- Corsair 750AX power supply
- LG DVD RW drive
- Monsoon Planar speakers and subwoofer
- Windows 7 Enterprise 64bit OS

I'm overclocking the CPU, and I'm at 4.5GHZ at 32 degrees C at rest and 75 degrees C at 100% CPU utilization. The board was extremely easy to setup, tweak and leave running. I've updated the BIOS several times and the last time (0064), I had to set my BIOS settings to "default" prior to applying the BIOS update and everything worked once I did that. I have never had a BSOD and the PC runs very well. I use the BIOS to update my settings (overclocking) as I found this is more reliable than the Intel Extreme Performance Utility that runs on Windows 7. All drivers are current and I'm 100% satisfied with this motherboard, it really shines with this CPU! I'm not a gamer (hence the GTX 650 video card), but I tested my son's GTX 660 OC video card in my PC and it was fantastic and the performance in the latest games (BF3, Crysis 3, etc...) was smooth and fast!

I use my PC for work and I use a lot of virtual machines and Oracle's VirtualBox runs great on this PC and the VM's perform just like an actual PC running that particular OS, which is what I wanted. Documentation is there, you just have to search for it on Intel's website and the accompanying technical information is staggering, if you want to read it! The Corsair 650D is a big, heavy case, but it holds all of the components, keeps them cool and I can't hear any fans at all, so it's doing exactly what I expect it to do. I read up on the issues some others had with this board, but I have not had any issues at all, so this is just another data point... I'm not an employee of Intel and have no financial interest in Intel, I'm just a very satisfied customer! BTW, I'll be installing Win8 soon and I'll update my review after that experience... Thanks!
