Pros: Great features in the BIOS.
Cons: First of all this motherboard is extremely picky when it comes to RAM. Using any other RAM then the RAM supported according to the QVL will cause you nothing but problems. Using high speed RAM that is supported according to the QVL will leave you limited to running dual channel instead of quad and will limit you capacity to only 8GB. I was unable to get any 16GB kits of quad channel RAM running at 2400mhz. I was able to get 16gb of 2400mhz running perfectly fine on my last motherboard but this one is extremely picky and for the price its not worth it. Also the specs for the PCI express slots are off and falsely advertised. Yes the slots are x16 but only run at x16 if you are only using one of the slots. Now why would I use just one video card on the motherboard in the 3rd PCI slot? Makes no sense at all. The PCI slots are: 2-way sli (x16,x16,x8,x8) 3-way sli (x16,x8,x8,x8) 4-way sli (x16,x8,x8,x8).
Other Thoughts: Don't buy this board there are plenty of other boards that have the same performance for hundreds of dollars less.READ FULL REVIEW
Pros: This motherboard came with every option I was looking for and was a decent price for what is included.
Cons: I have always bought Gigabyte motherboards and after owning this one I have been unsure about supporting Gigabyte products in the future. This board is the most unstable motherboard I have ever had and after upgrading the bios it is still very difficult to keep stable. It runs fine with one GPU in the top PCI slot but once you add 2 or even 3 cards for 2-way or 3-way sli this board becomes a big headache. Currently I am running 2-way sli because the board won't even boot if I have 3 cards plugged in. I'm currently using 2 Asus GTX 670 4GB in 2-way sli which are liquid cooled. Sometimes when I need to reset my computer for updates the bios locks up and won't boot up. The USB ports all shut off and you can't even enter the BIOS and the only way to get the computer to boot is to remove all the video cards and plug only one of them into the top PCI slot and it boots fine. I have switched around all 3 of my GPU's and tried all the PCI slots one at a time over a 6 month period to try to see if I had a bad PCI slot or GPU. I tested them each for weeks in each PCI slot and they all work perfectly fine by themselves. The problem only occurs when you try to do sli. This becomes a major pain to do when you are running all your cards on water!
There is also a major problem with the overclocking on this motherboard. I am not a noob by any means when it comes to overclocking because when I first got this board I was able to get it stable at 4.8GHz no problem but the board was very unstable when I set up sli. Now after flashing the bios to F12l its somewhat stable in 2-way sli (still 3-way doesn't work). It doesn't matter how I set the settings on my motherboard because no matter what I set it at I can't get my i7 3930k to overclock more than 3.2GHz.. I tried to flash it back to F11 and still the motherboard won't overclock anymore even when using the Easy Tuner Utility provided by Gigabyte. When entering the bios it says my core clock is at 4.6GHz but when I boot up into Windows 7 and check the clock in CPUZ, Easy Tune 6 and Windows 7 Performance information it only shows up as 3.2GHz with a boost clock of 4.0GHz which is frustrating.
Also the lack of updates for the drivers and the bios in over a year make me very stressed out from purchasing this board and having virtually no support from the manufacture. I highly recommend that everyone stays away from it.
Pros: My GTX 670 cards went from running 81*C full load down to 57*C overclocked full load. Very stable overclock to 1350 with K-boost turned on. Very impressed by the cooling capabilities.
Cons: I purchased these to do SLI in PCI slots 1 and 2 directly next to each other because my ASUS 4GB gtx 670's had poor air flow and would overheat very easily. The Fan for the RAM sticks out too much and you can't place the cards right on top of each other and I had to modify the bulky plastic so that I could fit my wifi card just below PCI slot 1 where I had my GTX 670 installed. I had to use my PCI slot 1 and PCI slot 3 because the top card just barely covers up my second PCI slot 2. If you do some modifications and remove the bulky plastic case and remove the RAM fan it is possible to get them to fit. The RAM will stay cool as long as you have a decent case fan blowing directly onto the cards but the RAM fan and the bulky plastic should have been designed correctly to address this problem.
Another thing that other people addressed and is true is that the installation was a pain! I was doing two of these at once and it took me about 5-6hrs.
The directions for the GTX 670 were also a little off and had incorrect spacers in the instructions which I had to adjust after first assembling the water block to the card. If you have a backplate already installed on your card like I did you have to modify the install a little bit to get the water block to fit correctly.
Other Thoughts: Its about time they dropped the price on these too because they aren't worth $100+ each.
If I was going to do this all over again I wouldn't recommend it. I would have gone with a Corsair CPU all in one liquid cooling set and bought a custom bracket to connect it to the GPU then add on some RAM heatsinks. This would have taken about an hour per card tops and that would only be because you would need to wait for the heatsink glue to dry.
