This is the 4th PC I've build from scratch. My previous one was built 1st quarter of 2007. It was an Intel Core Duo, or Duo Core, whatever. So with this machine, I bought the best of the best. And it is one of the fastest machines out there today.

So let me start off by saying, this motherboard has everything you could ever want, except firewire. It has plenty of USB ports on the back, and it has plenty of USB headers on the motherboard itself. I was able to connect up my USB 3 and USB 2 ports on the front of my CoolerMaster HAF X case. I was also able to add a front mounted memory card reader with an extra USB port using one of the motherboard headers, and I even had an un-used USB 3 header on the MB, so I bought a back bracket from ASUS themselves. So I think in total, I have maybe 15 USB ports on my machine, that are directly connected to the motherboard itself. No Hubs used here. LOVE IT!

I opted for the Corsair liquid cooled H80 system. So far, so good. No problems with over heating. Seems to stay a nice 25c under normal load. I haven't checked to see what it runs while in BF3 yet.

Since this thing has 8 DIMM slots, I bought 32GB of ram. Overkill for most of what I use the machine for, but will come in handy when I work on big After Effects Projects. I've always been bottle necked in the past by memory. My files get so detailed, that I can only preview a couple seconds at a time. So I an anxious to get a new After Effects project to see how this really handles.

I've run the Windows 7 64bit performance test, and everything runs at 7.9, except for the processor. It runs at 7.8. Kinda disappointing. But still faster than my 5.2 system previously.

Which brings me to the biggest gripe.

I'd purchased the new intel x79 3960x chip and had initially decided to go with the Asus P9X79 Pro motherboard since it was about $150 cheaper and I didn't figure there were many features on this board that I really needed since I'm not a huge overclocker, mostly a gamer and visual effects animator and didn't necessarily need the fancy in game overclocking dongle or anything. After I received 2 DOA of the P9X79 Pro boards (faulty DIMMS and USB ports) I decided that maybe I should just try something else entirely and threw down the extra cash and I have to say that it was a great decision, this board not only worked without fault, it has plenty of features and room to expand for the next year or 2. All of the BIOS based features are great and make it simple for even basic overclocking, I haven't really messed around with the dongle or done much in the tweaking of voltages but it appears to be very easy to do if I ever decide to. Asus has a great lineup of boards out to support this new intel chipset and have gotten great reviews around the net, I'd recommend this for any enthusiast gamer, or even creative professional looking for a great system board.

This board has nice and useful features, but mine did not detect all of the memory modules. it only detected 24GB out of 32GB. I increased the VTT and Memory controller voltages as suggested by some users but it didn't help. In bios the SPD information page shows all the modules and correct capacities, but in the main page it shows 24GB available memory. contacted Asus 3 times during the last 7 days, still no reply!

It seems too many people facing the same issue but no support provided by asus, so I am returning this board to amazon for a replacement and I will update this review once I received and tested the replacement board.

If you read reviews on other sites, there are many complaints about non included Battlefield 3, but for me it was included in the box, it was a download card with hidden download code. (Picture added)

My Setup :

Intel 3960X
Asus Rampage IV Extreme
Corsair H100 Cooler (Changed it's loud fans with 2x Noctua 120mm PWM)
OCZ RevoDrive X2 160GB (OS + Apps)
MSI GTX 580 Twinfrozr OC
Patriot Division 4 Viper Extreme 1866MHz (8 x 4GB)
LSI 8 Channel Sata III Raid card
Hitachi Sata III 3TB x 5 (Raid0)
CoolerMaster HAF 932
LG Blu-ray / HDDVD Drive
CoolerMaster Silent Pro 1000W Power Supply
Asus STx Xonar Essense
Windows 7 Ultimate x64
Seagate Barracuda 7200RPM 2 TB SATA 6 GB/s x2 (RAID1)

Everything works great on this board except the memory issue.

UPDATE #1 : Received replacement board from Amazon, The new board does not have Memory slot issue, Now all of my 32GB memory is accessible and everything works great. BTW still no response from ASUS!

Made all the differance, I had been struggling getting max resolution and keeping frame rates up on with my old X58 board and 960 processor. But this did the trick while still using my dated 5870 GPU's I went from 50 fps to 84 and increased the detail at the same time. I am convinced the extra cpu to gpu bandwidth did it.

Overclocking is a breeze, the bios does the work for you. With a few clicks I am running in the mid 4's with no issues. Hit the gamers preset, changed the ram speed to match mine and haven't touched it since.

I did not use the X-socket so not sure how well it works. Something about stacking and cooling didn't sit well with me. I also wish it had dual LAN connections.

The BF3 game was an added bonus, I do wish it came on disc instead of a download that required signing on with Origin, I like to keep my gaming maching as clean and lean as possible.
