I build custom PC's as a side gig and when it came time to build myself a new PC, I had a ton of motherboard to look at that Ive used in the past. Some of them I have had driver issues with, some lack a USB 3.0 header on the motherboard, etc. They all worked find but it was just little nit picky things that were annoying. I wasnt completely satisfied with the ones that I had used in the past Asus M4A89GTD PRO/USB3 Socket AM3 AMD 890GX/SB850 6 SATA USB 3.0 ATX Motherboard, ASUS Socket AM3/AMD 880G/USB3.0/Hybrid CrossFireX/A&V&GbE/Micro ATX Motherboard s M4A88T-M/USB3, ASUS M4A88TD-V EVO/USB3 - AM3 - AMD 880G - DDR3 - USB 3.0 SATA 6 Gb/s - ATX Motherboard so I decided to give this one a shot. I have to say I was very impressed. It had everything that I was looking for.

I love the graphical BIOS. Its not really a functionality difference but it does look nice. The USB 3.0 header on the board is nice so you dont have to route it through to the back side of the case and take up one of your slots on the back. It has SATA 6 gbps. It has 8 sata connections (I didnt realize that when I ordered it so that was a pleasant surprise). Will run AMD's new bulldozer processors and 2133 mhz DDR3.

For the money, I would say that this is second to none. It is comparable to the republic of gamers mobo but costs quite less. You really cant go wrong with Asus period.

Installed this new ASUS Motherboard in a new tower. It is amazing the amount of hardware this board has. It works great with a AMD 6 core CPU. Updates to BIOS is very simple and safe. Installed the latest 901 BIOS. The board has a USB 3.0 ports for the front or rear of your computer case. Has 6 SATA 3.0 ports plus 2 SATA 2.0 ports. Has 2 usb ports to add more usb hardware if needed. The audio is very good. I use a 5.1 surround speaker system. The BIOS is very easy to use and to Overdrive the CPU is done automatically through the ASUS program that comes with the motherboard. Overall, I give it 5 stars for ease of installation and personalization of the board.

Update: 01/07/2013 Installed Windows 8 Pro with a dual boot configuration. Unfortunately, This motherboard (Version 1.x) doesn't support the fast boot feature of Windows 8 but the newer version of the Motherboard does. Its the same as this board but version 2.0 which is fully compatible with Windows 8. But I still give it five stars. My tower has 5 hard drives, 4 dvd burners, one card reader, and two printers plus 4-4 gigabytes of DDR3 Ram hooked up to this motherboard. The ASUS Motherboard handles everything without any glitches at all. That is how amazing this product is. But the board ,like all new motherboards being manufactured today, doesn't come with an IDE port. So you would have to purchase a PCIe card adapter to add IDE hardware.

Well i purchased this motherboard last week and paired it with 16 gig of the Corsair Vengence low profile RAM, and the new AMD FX Series 6100 AM3+ Processor, I was able to finally get it all together this weekend and as soon as I turned it on there was a big red LED indicating a CPU problem and the computer would not post. After a little bit of troubleshooting, reseating the processor and etc, I finally called Asus, it was noted that even though this board is AM3+ ready they did not update the bios chip to handle these new processors, so they realized the problem right away and will be shipping me a new bios chip to install that should make everything work. Overall the motherboard is great, i liked the layouts of where everything is. But be ware if you do pair this up with the new bulldozer processors you will probably have to get a new bios chip sent to you to make it work.

Well built Motherboard with fantastic overclocking and management tools. The Windows tool set is great, but what blew me away was the UEFI BIOS. It has quick settings for conservative, normal and overclocked as well as a great interface for each and every possible setting in the BIOS.
Don't hestitate to buy this, Seriously! For all of you who like to buy the $75 to $125 range motherboards, Don't, I used to be that person. Sure am a happy camper I went with ASUS and not MSI.
Would recommend this motherboard to anyone.

I bought this along with an AMD FX-8120 8 Core Processor and a Corsair Hydro H60 series stand alone water cooler for the CPU. This computer is beastly easily overclocking to 4+ GHZ with idle temps remaining below 45C and 55-60C on full load. I am currently running with 16GB of Mushkin Ram, 2 GTX 570's in SLI, 2 patriot SSD, and windows experience index rates PC at 7.9 out of 8 on all components on Windows 7 Ultimate 64-bit. Benchmarks are also phenomenal and runs BF 3 in 1080P ultra settings with no screen tearing and over 70 FPS.

I was very impressed with the new UEFI bios and its easy overclocking utilities. So much so I also bought this motherboard for a AMD Athlon II Rana 455 triple core processor which I was able to easily unlock using the built in the BIOS tools. I have that PC now running with the triple core unlocked to a Phenom X4 B55 at 3.8 GHZ 8GB of gskill sniper series ram, crucial 120 GB solid state drive, and 2 Gigabyte gtx 560 in SLI. That is used for a variety of video encoding and light gaming Star Wars- The old republic runs on max settings without any issues.
