Pros: I needed a dual-ethernet Z87 board and this one delivers. Rock solid so far and running slight overclocks on my 4770K and Vengeance Pro memory. On-board audio is incredible considering it's on-board, and can hold its own against a decent sound card. Built in headphone amp is also a huge plus for my big Sennheiser headphones.

Cons: Two fan headers are in a weird place between the CPU socket and the first expansion slot. They could not be in a more inconvenient spot. Chose not to use them for cable management reasons. Otherwise I have had absolutely no issues with this board.

Overall Review: Not ugly like the Z87 Asus boards. Bleh

Pros: Lots of USB ports, AC wifi, Z87 chipset, lots of SATAIII ports, 4 case fan headers, 32gb RAM supported, UEFI BIOS, backup BIOS, CMOS reset button, debugging LEDs, heatsinks on chipsets where it matters, enough space for a reasonable CPU cooler w/o blocking a DIMM slot, legacy PS/2 port, PCIe 3.0, 1150 socket.

Cons: By far, the biggest con was the initial BIOS (ver 1.30) which didn't play nice with USB 2.0 devices (like your mouse or keyboard) on the USB 3.0 port when in BIOS. That was fixed by flashing to the latest BIOS. BIOS is upgradable via the internet directly from BIOS, but ironically, this feature too didn't work until I upgraded to the 2.10 BIOS. The next biggest con was really with the Intel Rapid Start software when installing on Win8 pro (but to be fair, this isn't ASROCK's fault). I eventually did get that to work, but I am still confused as to how I initially did it, and now I can't replicate the difficult I had even if I uninstall it, so go figure?

Overall Review: I used this MB in a Home Theater Server build, so I am not using the overclocking features. Parts in the build: Case: Silverstone GD08 w/3x120mm case fans Motherboard: ASROCK Extreme6/ac SSD: Kingston HyperX 3K 120GB (used for Intel RapidStorage and RapidStart implementation).

Pros: Fast Boot takes about 3 to 4 seconds from the moment I push On button. I use Plextor M5P for booting. Set OC to auto and I get 4 Ghz (can go a lot more, but no need) keeping the CPU temp. in 50 Cel or less. Updating the BIOS specially the 2.10 by Instant Flash was very easy and rewarded. No issues of incompatibility with any of the other hardware that I installed in the motherboard.

Cons: I just did put together this motherboard yesterday, it came with BIOS 1.3 and it was crashing often, updated to 1.4 and it was even worst. Luckily today was the release of 2.10 (thanks Asrock) and it works perfect (I went to pretty much everything in the BIOS, and even left the computer in BIOS for a couple of hours and no issues). The WiFi antennas are a little bit weak, don't be too far from the router.

Overall Review: The crashing or freezing was only in the BIOS, it never affect the OS at all. I'm using WIN 8 Pro.

Pros: I took a chance on this Asrock board as I usually only stick with Asus. I was happy that I did. I saved some substantial money, and have features that would have cost at least $70 more on the Asus side of the house. It works like a charm with 2 x SSD's and 3 x HD's, 32GB of Gskill Ares ram, and Nvidia 660Ti card. The bios was easy to use, especially in setting up HD's and boot order. XMP ram profiles were a single click. Good stuff.

Cons: None yet, other then I wish the Asrock A-Tuning utility would start up minimized. You want it to load at startup so the fan control software sets your profiles on startup.

Pros: Work right out the bios with i7 4770, Corsair plat, and EVGA GTX 670 with default bios no problem, might flash the new bios later will use the current bios for now. Home cloud app. is pretty good.

Cons: none

Pros: This motherboard is a bang for your buck. It has all the necessary features and more. It has a solid design and I have had no problems with it so far.

Cons: As of now, no problems have been encountered.

Pros: Lots of great features at a good price point

Cons: The first motherboard that arrived was DoA and the second one has an issue with the WiFi but even so the motherboard has a lot of promise.

Overall Review: NewEgg Premier helped a lot in salvaging the situation, their Premier customer support expedited the shipping of the replacement board and it allowed me to return the slightly defective motherboard with ease.

Pros: Once the BIOS is updated, this motherboard is rock solid (running 8.1). Temps stay cool, though I don't overclock and cannot provide information regarding performance settings. Intelligent layout; everything just seems to fit great. Excellent clearances for CPU cooling. I personally put a CPU liquid cooler and later a super-large Noctua cooler on this board with no problems.

Cons: I was unable to get the BIOS GUI to connect to the servers to download an updated BIOS. I was also unable to network configure the motherboard through the BIOS GUI. The USB flash BIOS didn't work for me either. Until the BIOS was updated, the BIOS GUI was unstable. The cable on the wireless antenna is fragile and probably incapable of withstanding pets or chidren. My bluetooth radio is showing a problem, but I'm not convinced that this anomaly is hardware-related.

Overall Review: I would purchase this board again without hesitation. I initially forgot to plug a CPU power cord into the socket, which made the board boot and immediately turn off, so I respectfully recommend that you be smarter.
