So before you buy this motherboard, take time to read the following list of positive and negative reviews of Asrock Z97 Extreme6 in terms of performance, build and price.
Overclockers point of view:
"With this newest Intel chipset (and set of motherboards) there are more incremental upgrades than performance boosts. The most notable of these upgrades is Haswell Refresh and upcoming Broadwell CPU support along with M.2 SSD support. I’m normally a “bad news first” person, so I’ll mention the bad things first. Alright, I’ve got nothing. This board has no issues that I was able to find! It is stable when pushing the limits, has an awesome UEFI, and is bundled into an attractive design. To top everything off, this board is loaded with features such as Dual Gigabit Ethernet, Ultra M.2 (32Gb/s), Thunderbolt, Purity Sound 2, 10x SATA ports, and 3200 MHz DDR3 support.
From an overclockers point of view, this board has all you need to push for every last MHz. Integrated power/reset switches for open-air setups, BIOS chips that are a quick swap from new, a BIOS reset button, a physical BIOS switch, 12 phase digital power delivery, and a slew of overclocking options in the UEFI.
Flipping the coin, the ASRock Z97 Extreme6 comes in at an extremely competitive price. It is currently $169.99 at Newegg, beating out a very comparable Maximus VII Hero by $50! This price point makes it a great board for most budgets looking at the unlocked Intel CPUs. Now for the rating. Stable? Very. Looks? Amazing. Features? Loaded like a Cadillac. Add to this great overclocking capabilities and the amazing price, and I’m wishing there was something above “Approved”!"
Techreport point of view
"Even though the Extreme6's hardware spec hits a lot of the right notes, the board still falls short in a few important areas. The I/O shield is littered with metal protrusions that can slice fingers and get caught up in the rear ports during installation. Also, there are no provisions to simplify the wiring process for front-panel connections. There's no way to boot directly into the firmware, either, though ASRock provides a software utility that reboots into the UEFI from Windows."
