Summary: I decided to go with the dual cpu system but only buy one of the chips, which would allow me to spend the money in a much faster chip with the ability to add on additional one later. Instead of two $880 CPUs, I spent $1600 on one faster chip with a much better benchmark. I went this route because it would allow me a good working computer with continued upgradability when prices come down to a more reasonable range. I am about $6000 in already on this computer.
Summary: I haven't had the board very long, so I can't speak to its stability, longevity, etc. But thus far, I'm pleased with it, overall.
Pros: The board has a rich feature set and supports a wide array of components. It seems to be very well built, as well. I found the BIOS quite simple to work with, so I'm not sure what difficulties the one previous reviewer was referring to regarding that. I had absolutely no problems whatsoever setting up a RAID 1 array for my main system drives. Actually, it may have been the easiest set up I've ever done.
Cons: I'm going to list several "cons" here, but I'm being pretty picky on some of them. First, as others have said, this is NOT a standard eATX board. I put this in a Corsair Obsidian 750D case, which is eATX compatible. However, of the 10 holes in the board, only FIVE of them lined up correctly with the eATX holes (no, I'm not joking). As another reviewer stated, I too had to drill and tap holes in the case to get it to mount correctly (he said he only needed to drill/tap...
Summary: This motherboard is working perfectly for me. PROS: -The motherboard has plenty of useful features. -Great capacity for RAM. -A great size considering the amount of RAM that is capable of using and the double socket. CONS: -BIOS could be better. -Really bad Fan control, at least without PWM fans. -The mounting holes are not standard E-ATX or SSI EEB, you have to slightly mod your case in order to mount the motherboard.
Pros: Bought them in bulk, all working smoothly. one ram slot is not working in one board I received, but changing my ram to another slot makes it work. This board has everything I need for a server machine.
Cons: single DOA ram slot is my only disappointment. But i am satisfied with this low failure rate.
Summary: Good: Outstanding features, PCIe 3.0, a good number of slots, Very stable if you don't mess with BIOS to try and get Windows 8/Server 2012 running. Facts: EATX form factor = large size, while I have dealt with large size before, this just seems bulky, and the need to shoe-horn the MB into a case. Also only 1/2 of the EATX mounting holes lined up, so I had to use the good old, white motherboard standoffs from before the industry started to standardize.
Summary: For those who are interested, in an attempt to see if, perhaps, some of the components were faulty, I placed the GPU (an NVIDIA GeForce GTX 680) in an ATX-based system and found that it worked perfectly. Further, I verified that the PSU (COOLER MASTER Silent Pro Gold Series RSA00-80GAD3-US 1000W ATX 12V v2.3/EPS 12V v2.92) worked on two different ATX-based systems.
Pros: I'm sure there would have been plenty if the board would have worked.
Cons: Motherboard was basically faulty and when testing the setup on my workbench, with the power-button cable from the case properly connected, I found that the motherboard would turn on automatically once: (i) the 20+4 pin and two 4+4 pin 12V connectors were attached to the motherboard, (ii) the PSU switch was flipped to on, and (iii) without pressing the case's power button. Further, all of the other components, except the GPU/GPU fan, e.g., the HDDs, the optical drive, ...
