The next generation of Intel's core i series isn't a major upgrade from the previous, but yet an upgrade no less.

This board won't blow you away from the 2nd generation sandy bridge, but you probably already know that prior to reading this. What this board will offer is PCI-E 3.0, I don't know if native or not, and some other enhancements over the previous generation.

The extreme6 seems well rounded for what else is offered. The extreme4 isn't bad either, but the extremem9 has wifi if I recall right which I have no use for since I bought the internal adapter long ago. So after all my research and looking I chose the extreme6 and have been quite happy with it.

When you buy a new board, I am not professional but I advise strongly to update the bios or look into the proper bios updates... which many people overlook and don't find a concern. Maybe problems are solved this way, just a side note.

With that said the UEFI is quite nice for a much friendlier user environment vs traditional BIOS. The overclock abilities in this board are quite flexible. Indeed there is the lazy option, or easy option for others, that will overclock the CPU automatically to a few different levels. Starting at 4.2ghz(if I remember right) up to 4.8ghz. Also there is a Turbo 30 option, which I have researched and found to be a quick 30% performance overclock. I choose not to use either of these options. Should you be an overclock genius who loves to touch all the settings, such as tweaking the specific in and out voltages(if there is such a choice for output voltage) and all other such choices you have that power.

This ASRock Z77 Extreme 6 motherboard is all it's advertised to be and then some. Packaging and inside packing was excellent. Comes with nice SATA cables, SLI bridge, etc. The instruction manual is good, but could be improved on, however, the CD has a PDF manual on it that is much better.

The board was easy to install. My system is:

ASRock Extreme 6 MOBO, Laser 1000 PSU, EVGA GTX 570 GPU, running my LGA 1155 2600K for now (I plan on upgrading to the Intel LGA 3770 soon), 16GB Corsair Vengeance low profile Blue 16GB (4x4GB) DDR3 1866 MHz (PC3 15000)CML16GX3M4A1866C9B RAM, Zalman CNPX 11X (Extreme) CPU cooler, Samsung Optical drive, Windows 8 Pro.

The board ran perfectly out of the box and still is. The BIOS system GUI interface is clean, gives a lot of options and is easy as all get out to OC. I literally was blown away by how simple and straight forward it is. The included CD has lots of nice add on's but you don't need to install them for the board to run perfectly.

I have built several systems using EVGA and ASUS MOBO's but on this one, based on several reviews and research, I decided to give ASRock a shot because for the money, the quality and the specs I felt it as a worthy contender with the likes of ASUS, Gigabyte, EVGA, etc. So far, I was right.

This is a great board for those who want solid performance, great OC potential and a board that not a lot of colorful eye candy but is most certainly capable of delivering the sweet taste of speed, reliability and stability and easy on your wallet.

Finally upgraded a gaming rig to a 3570K and needed a new board. The old rig was developing SATA issues, lockup/audio loop problems and had never really run very cool - even at stock speeds. The new system screams, and with H2O cooling is staying under 40c at all times.

This board posted right the first time the power was flipped, recognized all 16gb of ram, the cpu and both the HDD's and the SSD's, and prioritized correctly. It will try to set drive modes wrong if you are mixing SSD and HDD, but it's an easy fix and didn't prevent boot up. The bios update stalled on me (apparently a common event), turning the whole system into an incredibly pricey brick pile, but with google and a thumb drive I got it fixed a little later, but prior to that I emailed ASrock explaining the problem and asking for a solution. The did not give an email solution but DID send me a new bios Eprom without hesitation, and they did respond to all emails - not all board makers will (trust me). In retrospect, upgrading from a thumb drive or CD would have saved me a day of panic, had I taken that route the first time.

I waffled between this and the Extreme4, and I'm glad to have spent the few extra dollars for the 6. Lots of SATA ports - double the S3 - 1394 and ESata on the back panel, etc. - an almost perfect board for my build. Other boards won't allow the install of a crossfire setup and still have access to an X1 slot, which I thought I needed for my Xonar - this one does, but more importantly, the onboard audio is very good compared to several iterations ago, and I ended up not needing it after all.

The bios is unusually flexible and very easy to navigate - great for tweaking without being SO detailed that you burn things up or tweak it until it won't boot.
