MSI Z77A-GD65 - In The Box
The MSI Z77A-GD65 is currently available for $190, just north of the Gigabyte board. With this in mind, we also get a few more extras in the box than the Gigabyte:
IO Shield
Driver CD
User Manual
Certification of Military Class testing (FWIW)
Four SATA cables
Flexi-SLI bridge
M-Connectors (to help front panel connections)
V-Check cables (to help with voltage read points)
Voltage Readings
Using OCCT we monitor the voltage change of the motherboard under load. This represents the direct correlation between the Load Line Calibration and how the processor/motherboard deals with voltage requests while under load. This is not to be confused with the quality of power delivery, but more an indication of how aggressive the default LLC settings are on a motherboard.
Similarly to the ASUS board in this review, the MSI has minor variations in the CPU voltage. Worthy of note though is the lower VCore used by the MSI board compared to the other boards in this review while at load, suggesting more aggressive LLC settings.
Overclocking
Note: Ivy Bridge does not overclock like Sandy Bridge. For a detailed report on the effect of voltage on Ivy Bridge (and thus temperatures and power draw), please read Undervolting and Overclocking on Ivy Bridge.
Overclocking options on the MSI Z77A-GD65 are relatively straightforward. With the OC Genie button on board, give it a press and it lights up, causing the next boot to initialize a series of predefined settings for an overclock. Manual overclocks can be done by the Click BIOS software in the operating system, or by adjusting the BIOS directly.
Automatic Overclocking: After pressing the OC Genie button, it essentially seemed to enable the Enhanced Turbo option in the BIOS. The system booted without issue, and I was greeted with a 39x multiplier under all loads, showing 1.080 volts and 65ºC with PovRay. This is a rather disappointing automatic overclock. This is also indicative of issues relating to one button overclocks - the manufacturer is supplying a series of presets that has to work on every processor out of the factory. It is perhaps time that MSI introduces their own stress-testing overclock into the mix to get a better result.
Manual Overclock: Given the previous overclocking results achieved, with the MSI board we jumped straight in with 1.2 volts, with PLL Overvoltage enabled just for good measure. At this voltage, 46x multiplier was the highest multiplier stable, giving 82ºC with PovRay and showing 1.184 volts at load. In order to get the 47x multiplier to work, it required 1.250 volts on the CPU, although this gave 90ºC during PovRay and 1.240 volts at load.

Yes, it is a very important feature. The Ivy Bridge IGP can drive 3 monitors. 4 display outputs means 3 of them are digital.Discrete GPUs increase idle power consumption, an as of this post none of them have particularly good open source drivers. Some of us just want lots of screens, good compiz performance, and silence.

I have been building a series of matx htpc/gamer machines.I have one with the basic
Gigabyte GA-B75M-D3H mATX board
and one with the
Gigabyte Ga-h77m-d3h mATX board.
I want to decide between
the ASUS P8Z77- m pro mobo or
the ASUS p8z77-m board and
last but not least the
Gigabyte Intel Z77 LGA 1155 AMD CrossFireX/NVIDIA SLI DVI/HDMI/DisplayPort Dual UEFI BIOS mATX Motherboard G1.SNIPER M3 .
I am liking the two builds I did with the lowend gigabyte boards and some intel i5 t2500t cpus I want a better board but I don't have many reviews to go by.

It just doesn't make a whole lot of sense to me. Are most DIY'ers really opting for ATX? Should they? I'd bet most people only plug in a video card and maybe one other card such as wireless or even a tuner. Every other possible need they may have would not only be met by mATX but even ITX is pretty full featured these days.You'd think mATX would be what most boards are targeted at, and leaving ATX for extreme builds/bragging rights. It's just like those high end video cards, most people don't buy those, rightfully and importantly so. Those should be the premium prices, and mATX should have a lower price. The focus just feels off.

You mentioned people want mATX board. There by itself probably means that it can command higher prices, due to higher price tolerance of the purchasers.Caeric - Monday, May 7, 2012 - link
Enjoyed the review. I still have an old AMD dual core, and I'm considering a new system in the next couple of months so these help a great deal.I did find one error in the article, under the ASUS board:
"The ASUS P8Z77-V Pro retails at $225-$235, essentially $100 less than the ASRock Z77 Extreme4..."
It should say "...essentially $100 more than the ASRock..."

Curious as to this controllers' performance vs the ever present Marvell controllers. Does it use a pci-e lane or usb3 for it's bandwidth?FozzyofAus - Monday, May 7, 2012 - link
Great review.I'm leaning towards mATX as well for this build as I've never used more than four expansion slots and currently I'm only using 3 (one is USB3 which won't be needed in the new board).
I'd like to have a bit more room in my current case and the option to reuse this motherboard in a smaller case in future if I upgrade my main rig to Haswell next year.
Any chance of adding Asrock Extreme4-m to the next motherboard roundup?

Sorry guys but this review was a bit average. Comment on the various different controllers used by the motherboard manufacturers but don't offer any kind of review on them?The good additions: DPC latency and boot time.
The missing? Well everything else.
I was especially hoping for a comment on the VIA audio on the UD3H - it's been a while since I've seen VIA codecs on mainstream boards.
I'm also amazed that you didn't slam the ASUS board for it's price and lack of features. Realtek 892? On a board that's nearing twice the cost of the ASRock? Seriously?
No comment on the durability of the boards either? Hrm. No separation in testing of the different controllers on each board?
A bit lacking, sorry.

Perhaps you're commenting on the wrong review.As Ian stated multiple times throughout the review, Asus is using Intel NIC's on their boards, in this case, the Intel 82579V.
Durability is a function of time. Please point out the other motherboard reviews that covered durability.
spronkey - Thursday, May 10, 2012 - link
He stated ASUS were using Intel, sure. But didn't get into any details other than stating they exist about the fact that there are multiple USB3 controllers and SATA controllers on each board. No benchmarks comparing them etc.In fact does it even mention which controllers were tested?
And Durability is a function of construction quality and time. It would be nice to see comments on points such as board weight and flex, quality of soldering, quality of components used on the board (according to an electrical minded person on OCN, Gigabyte uses significantly higher rated MOSFETs than other manufacturers), temperatures of chipsets and VRM circuitry. These are things I can't easily find out by reading manuals.
