Experience: 3 Years
-Lots of on board connectors.
-Supports AM3 & AM3+
Works great, no complaints, I don't over clock or anything, so it's working amazingly as is, lots of connectors on board etc...

Experience: 1 Months
-very good overclocking
-lots of usb ports like motherboards should
-easy setup
the firewire is kind of useless
good board overall for any amd build.

Experience: 2 Years
Stable and handles whatever you throw at it.
wasn't free
Love this board stable under over clocking that would make your mama cry.

Great looking Motherboard
Great price
lots of usb connections
Works well with Amd fx 8350 and Gskill Ripjawsx ddr3-1866 cl9 2x 8gb

Experience: 2 Days
 Verified Owner
seems to do the job
big vrm hopefully it works well with the big fx chip when i get it in
-bios seems to have alot of issues when rebooting
-the 2nd fan only does max and there is no option to change ( got a bunch of silent fans and having 1 running at full bore kills the whole point )
if u get this with the h100i gt make sure you get the dam corsair link cord in b4 placing it had to pull it off a few times cuz of it

Experience: 5 Days

Bios options. Beefy VRM. Revision 4.0. Upgrade path for my 1090t.
Sata connectors are on the edge, not so easy to fit cables.
Handle overclocked 1090t with no problem.
My cooler is the weak point here...

Experience: 2 Months

-Sleek design(black on black)
-came in rev. 4
-price point (got it on sale for 119.99)
-many possibilities to expand in the future
-It works right out of the box
-none so far
Very affordable for what you get! Was very surprised when i opened the box and got the rev.4. Paired this with a FX8320 oc at 4.4mhz and runs very silent even at high load. I would highly suggest for high end builds but bare in mind no air cooler if u oc over 4.4 for it will heat up. Right now im using a cooler master hyper 212 evo and at idle im getting about 9c and at load 64c. Also ive added several extra fans in the case to achieve these temps(4 noctua nf12 120mm fans and a pci slot fan under the video card as exhaust so that the hot air from card doesnt go through the case). Overall im very impressed with the mother board, very easy to over clock if you know where to look. I do admit there is a lack of options but lets face it for the price point, it's well worth it. UEFI bios is very easy to comprehend (overclock multipliers, voltage, ram overclock etc.)

Affordable, Reliable Brand, One of the best AM3+ Motherboards you can buy.
I purchased this motherboard to go with an 8320 build and I am impressed with it so far. It has all of the features that you would want from a high end board without that $200+ Price tag. If you are planning on making a build with an AMD system, I would highly suggest you take a look at this board.

Experience: 2 Years
Runs my 8 core amd 8150fx and 8320fx in most applications without problem. Usually is on sale as well, cheapest 990fx board and that may be for a reason...
running with 8 cores during a benchmark (prime 95 or similar) the northbridge seems to thermal-throttle. There is also no temp sensor for the NB, meaning it took a long time to diagnose the problem.
The bios also lacks decent overclocking settings and has almost 0 fan control options. You can set 1 cpu fan as far as I can tell.
If you wish to overclock, or even to push your stock 8 core to 100% capacity, you will have thermal throttling in seconds. (i've read the NB temp with other sensors, and i've seen it at 80C+) The rev. 4 (this is the 3.0rev) has a heat tube which may well solve this problem, and that is why this board is on sale all the time. My buddy has a 6 core phenom, and overclocked to 3.8ghz it still experiences thermal throttling. This board also experiences a decent amount of vdroop, more than I would have expected from a $150 mobo. I have lost my faith in gigabyte with this product, and now i'll stick with asus.

I have experience with no less than 4 of these boards, and they all experience the same thermal issues and vdroop. For a non-overclocker not expecting to push his cpu this is fine, but there are much cheaper options if you want to buy a cheap mobo.
If you don't believe there is a lot of info on the web about this board and it's thermal issues.
