4 out of 5 eggsnot bad

Pros: Supports DDR3 1866 without overclocking.

Cons: System will not hibernate with new motherboard. It starts back up after a minute or so after hibernation starts.

Included software just okay, no tweaking some things like CPU shutdown method. I'm pretty sure that's why it won't hibernate.Windows monitoring software is weak, basically an ASUS version of CPUid.

It didn't ID my RAM properly, I had to manually set it to match the RAM ratings.

I don't like the RAM clips, they only appear on one side. We'll have to see if RAM falls out.

Other Thoughts: System Specs:

ASUS M5A99FX Pro motherboard
8GB Mushkin Enhanced Redline DDR3 1866

4 out of 5 eggsalmost great

Pros: Awesome bios. Quality board, seems very durable and not prone to cracks. Manual CMOS clearing buttons and troubleshooting LED's are a nice touch. Allows for 4 USB 3.0.
If I could give 4.5/5 I would.

Cons: The I/O panel is either poorly designed or improperly executed. This caused a great deal of trouble when mounting the board to the case. I had to glue tiny o-rings onto the case standoffs to raise the board ever so slightly to make the ports align properly to the panel. Tedious, and makes me wonder whether the o-rings might impair the grounding, though I believe it is grounded adequately in other areas. (I think these rings may help cushion and prevent cracking the board if the case is dropped) This extra step is not the case's fault! Either the ports on the board itself, or the holes in the panel for the ports are off. Or both.

Other Thoughts: Despite the annoying installation, I believe ASUS motherboards are the best in the industry. This particular board is great for my build, which to me is an awesome gaming machine. There are better crossfire boards out there but the value of this board is hard to overlook. Plays well with AMD Vishera 8350 and GeForce GTX 760, which it can support 4 of (I will probably never need)

5 out of 5 eggsGreat foundation for an affordable workstation

Pros: Though now ancient, the 990FX chipset provides a large number of PCIe 2.0 lanes for GPUs and expansion cards, plus SATA3. Onboard ASMedia USB 3.0 and SATA chipsets are recognized in linux (Ubuntu 14.04). Though not stated in the specifications, processor support list includes high TDP 220 watt processors.

Board also includes ECC and IOMMU support at a fraction of the cost of the competition. ECC in particular is becoming harder to find outside of expensive server parts.

Cons: Not PCIe 3.0, but each x16 PCIe 2.0 slot is a PCIe 3.0 x8 equivalent anyways. Just throw more lanes at the problem, right? Only 6 expansion slots vs. 7 for many competing boards. One slot is wasted on PCI (though it is below a PCIe x16 slot, so use that one for your double slot GPU and not feel so bad). Cost-cutting Realtek chipsets for audio and LAN (understandable). Mail-in rebates are scams.

Other Thoughts: If you are looking for a well-rounded board for a workstation, there isn't a much better choice for the money. Though the compatible processors aren't the fastest, you get ample expansion and "good enough" performance, plus server and workstation class features.

1 out of 5 eggsDefective New Motherboard

Pros: It has great features and comes from Asus if it worked. I think Toms Hardware might have a friend at Asus because I now wonder about them too from a credibility point of view.

Cons: Brand new board with new Fx-8350 Black CPU that I paid to professionally assemble by a Texas computer company. The audio does not work. I spent 5 1/2 hours trying to get help on Asus 812-282-2787 technical support line. When a woman finally answered, she gave a set of instructions on VOIP line that I just could not understand. She gave no RMA and said for me to call back. I then spent another 3 hours on hold before getting disconnected. ASUS is have QC problems and customer support is not what it once was.

Other Thoughts: I am throwing this new but defective motherboard away and buying a different one. Very disappointed in Toms Hardware recommendation and also ASUS, neither are not the same quality they used to be. The phone call occurred during the morning and the afternoon on August 30. I hope someone from ASUS reads this and gets with their QC manager. I have bought ASUS products for nearly thirty years and always thought them as the best.

5 out of 5 eggsworks well, recomended

Pros: owned and built this unit in november 2013. still going, no glitches. iv been running a fx6300 overclocked from 3.5 to about 3.875 the entire time since the build. no issues. asus makes the most consistantly solid and stable boards through the various generations imo. you gotta update bios, as with any board when you finish your build, but asus is real good with updates. i updated at build, and i'v had no problems.

Cons: none i can think of.

Other Thoughts: a lot of the negative comments i see, i generally attribute to people not updating bios when they finish their build.
i used a ZALMAN CNPS9900ALED cpu cooler with the fx6300 and CORSAIR Vengeance Pro 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 Desktop Memory Model CMY8GX3M2A1866C9B (Blue) and a MSI Gaming N760 TF 4GD5/OC G-SYNC Support GeForce GTX 760 4GB 256-Bit GDDR5 PCI Express 3.0 SLI Support Video Card. corsair RM650 650w psu. kingston ssd v300 240gb. the package has been flawless so far.

2 out of 5 eggsBe Wary

Pros: Works well...when it works.

Cons: Lots of glitches,Horrendous Support

Other Thoughts: I am currently attempting to RMA this board for the 2nd time. It came back to me still faulty, although it was "repaired".I recieved no report on what was done, and they failed to return the mounting hardware for the heatsink. I talked to support again this weekend,and was told I'd have to ship it to them again (at MY expense). I was told I'd receive an email to authorize the RMA, but I have received nothing, and numerous emails have gone unanswered. I have been without a working mobo for 7 weeks now.

1 out of 5 eggsI'm done with ASUS

Pros: came in a nice box, nice layout, and has the 990FX chip set

Cons: bad video and hard drive controller. Typical ASUS it doesn't work and needs to be sent back for RMA. Every board I got from ASUS since 2007 have all been RMA'd with the exception of one P5Q Turbo. ASUS is living on their laurels at this point and I won't ever buy another ASUS product ever again so please Mr ASUS rep please do not message me back and call me a valued ASUS customer because I under no circumstances will ever buy anything from your company again

Other Thoughts: I built this computer for a girl who needs it for graphics design so she can make money to feed her kids. I used 2 different hard drives and 2 different video cards (an HD4870X2 and a GT560Ti) and nearly burned both cards up due the video controller. I used 2 different hard drives and did full installations of win7 ultimate and after 4 hours on each drive it has at best 67% of the updates installed. Thats with 12 gigs of DDR3 1866 ram so that is the hard drive controller. This board was bad from the get go because ASUS lived up to their reputation of living on their laurels. Lets hope they end up like Abit and BFG and are not around anymore releasing an inferior product

1 out of 5 eggsBad Board

Pros: Good features if the board would work

Cons: Extremely Poor Quality and Customer Service

Other Thoughts: Avoid this board - its a total lemon. In the last 6 months I've had to replace this board 3 times. Each time requires an agonizing RMA/Support and living without a board for the 2 week turnaround to ship and receive a new board. I've been a long time ASUS customer but I will be looking elsewhere for my next board.

4 out of 5 eggs

Pros: Love the BIOS. Everything is a pro save the one con listed below.

Cons: Would easily give this board 5 eggs except for one minor problem I ran into. Let me preface this by saying I should have read the specs more thoroughly and it wouldn't have been an issue. There are too few fan connectors for any well built gaming pc. It was a simple and cheap fix as I just biught two Y splitters from NewEgg for like $6 but would have loved one or two more connectors on the mobo since splitting them means I cant control the speeds on them independently. Other than that, great mobo.
