Also not cheap. Comes with all the bells and whistles you'd expect from a high-end OC motherboard and if I'm being honest, even though I appreciate it, I don't put even half of the stuff to use.

from completed build The SaberWulf

Best mobo I ever had. Had everything I needed. Lots of USB ports, plenty of SATA ports, 4 PCI express slots, USB 2.0 and 3.0 front panel connectivity, and so much more! 32gb ram support. AM3+ MONEY WELL INVESTED!!!! Buy this board. You wont regret it. Unless you get unlucky and get one thats DOA. Otherwise, you cant go wrong!

from completed build Updated Gumby

This has to be one of my favorite parts of the build. It just looks tough, has a great BIOS and I love that I can flash things at the push of a button or load the BIOS at the push of a button. Very heavy duty and makes the insides look pretty. The USB 3.0 slots are a bit picky at times and gave me quite a few problems when trying boot from my thumb drive which is the only reason why it gets 4 instead of 5.

from completed build an IT student's 1st build

nice and clear BIOS. easy to navigate. There are some motherboards that are cheaper and can do the same stuff, but i chose this model because it was highly rated on amazon.

from completed build Our first build

Fantastic MOBO plus a 5 year warranty, nice job ASUS.

This is the best MoBo i have ever had. It looks so sexy and the Features are awsome. It holds the voltage so constant. the only bad thing i have to say is about the audio quality. It is not Eargasm. I think it comes, that the audio pcb is not isolated from the other pcb. but only my thought.

from completed build First Build From Scratch

Overclockers dream, Easy BIOS Flash capable, AI tweak makes it simple to OC, Thermal Radar makes it easy to control temps in the case. No complaints about this product at all.

from completed build Critical Orange-2012-Upgrade

This board is simply fantastic for overclocking. My current favorite BIOS to work in, and the fact that it has two PCIe 3.0x16 slots, it made upgrading to a Crossfire setup super easy. Can't say enough good things about it.

from completed build The White Sails

Best AM3+ board out there, next to the ROG stuff. Lots of customization options, great features.

from completed build My Second Build

No complaints other than the time it tried to OC my CPU to 5.1GHz on first boot. Then again that was most likely user error.
