The features seem endless. Its UEFI Bios are the first I've encountered. So I can't give fair comparison, but I can say it was very intuitive and came with ease.

Overclocking is offered in an automated fashion for the novice and detailed menus for the advance user.

Supports 2 and 3 way SLI and includes the bridges necessary. However, it only came with a 2 way Crossfire bridge.

My only complaint was when I placed the cpu into the socket and began to close the enclosure, it felt a bit too snug and seemed to require a lot of force - the kind of force you would expect if you were installing a processor into the wrong socket.

While this is an expensive motherboard, I believe it is feature rich enough to justify for the enthusiast.

Wanted to post a few bits of info I found out by trial and error.

1. Make sure to push in your RAM. It only clips one side and the side without does not seat firmly without pressure.
2. When updating your Bios you need to put the new bios file on a thumb drive formatted to FAT32 before your EZ flash will recognize it.
3. Careful using the Marvell 6GB SATA ports. Be sure to plug your primary drives into the Intel 6GB SATA and only use the Marvell for storage. (or not at all)
4. You can go SLI X16 on both cards if you put something else in PCIE slot 1 (like a sound card or wireless NIC) This will kick in the NF200 and you can use slots 2 and 4 with full x16. (Although some people say not to because the NF200 causes lag.)

Overall a 5 star board and well worth the money. The OC options are amazing.

I really loved this MOB when I first got it...but now after about a year or os, not so much...the overclocking that is supposed to be such a breeze, not so much. In auto mode the thing cycles forever trying to find an acceptable setting, manually it's a crap shoot. The board does not recognize memory over 1300 mhz. It has to be overclocked and again not that easy. It does run stable in default settings, but that isn't why you get this MOB...

This motherboard and its BIOS makes is so easy to overclock the CPU. Building a computer is easy, but overclocking it is another thing, and I think the more you learn about your system and how it works the better things should get! NOT!!! At least for me. I've always struggled when approching overclocking of about 15% or more, but not any more. With the Maximus IV Extreme Z I'm running at 50% and stable. The Bios includes so many parameters to help with overclocking, most of which have an AUTO setting...the setting I use most. I'm overclocking an i7 2700K...and for now I have place #5 at PassMark, System Benchmarks;[...]
Even though it's not indicated the clock speed of the CPU was 5150MHz (103 x50). For me this would not have been possible without this ASUS board.

It became clear to me when I booted up into the BIOS that I will NEVER use all the overclocking options this board has to offer. That being said, I can rate this up from 3 stars for my stupidity of thinking it will work with an Ivy Bridge chip out of the box. For those of you who made that mistake, there's a DRAM issue with Ivy Bridge, because of the BIOS version. You HAVE to upgrade the BIOS using a Sandy Bridge (2nd gen LGA1155 2xxx series core i'#') to a 3xxx BIOS before using Ivy Bridge chips. Otherwise, you'll get a debug 55 LED code and you won't be able to even boot up. If you read the manual, debug 55 is 'no memory installed' when clearly, the DRAM LED lights up (this is controlled by the CPU, NOT the memory). After a painful process of asking ASUS what was wrong, I finally realized my mistake after days of research.

As for the board itself, do yourself a favor and get a Z77 board if you're not a massive overclocker. I learned from trial and error how to overclock my Ivy Bridge processor from 3.4 to 4.6GHz stable with 1600MHz RAM. There was an issue with the ability to go from 8GB to 16GB, but my CPU cooler is way to big. Thank god the red slots were far enough away to install my Corsair Vengeance. Be sure to purchase low profile RAM if you're going something like a Hyper 212 for your cooling solution while filling up all the slots. I'm using Cooler Master V6GT for both my builds, and the Extreme-Z makes RAM a problem. Thankfully, I decided to keep a minimum and go 8GB rather than 16GB, so all I needed were two sticks on the red slots, which fit and worked perfectly. The UEFI BIOS is amazing. It will detect every setting you have from what type of SSD you're using to what kind of COOLER you're using (if you have it plugged into the mobo).

Cons:

First and foremost, let me say that the PCIe slot placement on this board is terrible. Unless you want to run a single doule-wide GPU off of the NF200 (slot #3) or in the fourth (8x as opposed to 16x) slot, you only have three extra PCIe slots that will accommodate expansion cards (one of which will block your GPU's intake). Running a double-wide GPU in slot 1 (16x - a "proper" or "default" setup) blocks slot #2 (1x) and makes slot #4 useless for anything but another video card ("reserved for CrossFire/ SLi" according to Asus Support). I bought this board thinking that I would start out with a single GPU "jack of all trades" build and then someday go to an SLi setup and in the meanwhile populate my PCIe slots with other components. So I bought an ASUS Xonar audio card, an ASUS WLAN card and a Hauppauge TV tuner to go with my EVGA GTX460. Now, if I want to run all of the cards concurrently, I am stuck running the GPU off of the NF200 (slot #3) unless I want to run it in slot #1 and then block it's intake with the WLAN card in slot #3 and let it overheat.

Now, I may just be nit-picking but the CF/ SLi reservation issue is not documented ANYWHERE (even in the motherboard's manual, which I read cover-to-cover prior to purchase). Asus Support told me that this was incorrect operation - that I had a dead slot - and I sent the board back to Asus THREE times before anyone would even tell me about this. PCIe standard dictates that "if it fits, it works". Not so, on this board. Many of the people I talked to in the support department wouldn't help me with my issues any further than "its broken - send it back in, again, and we'll check it" and then "nothing is wrong with it - here's the exact same board back".
