Four Multi-GPU Z77 Boards from $280-$350 - PLX PEX 8747 featuring Gigabyte, ASRock, ECS and EVGA

Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows starts loading. (We discount Windows loading as it is highly variable given Windows specific features.) These results are subject to human error, so please allow +/- 1 second in these results.
Both the ECS and EVGA motherboards offer big POST time gains when controllers are turned off, whereas the ASRock is very quick by default. The G1.Sniper 3 on the other hand gives us the slowest stripped time out of any motherboard tested.
Overclocks
Here at AnandTech we want to provide quick and easy ways to determine if a board is good for you (with in-depth analysis of course). So here is a quick round up of our overclocking results. Overclocks are tested for stability with PovRay and OCCT - while these may not be the most strenuous of stability tests, it does offer a quick check for memory errors under high load (and also balances testing time with getting the next board on for review!).

10 years later, people be looking for how to build system with 20+ GPUs lmaomayankleoboy1 - Wednesday, August 22, 2012 - link
Where are the GPGPU benchmarks? AFAIK, those are affected by the PCIE 3.0 bandwidth, as shown in the HD7970 review.Games are more or less happy with a PCIE2.0 x8 .

A few GP-GPU apps are affected, most aren't. Even PCIe 3 is slow as hell from the perspective of the GPU, so you try to avoid external communication as much as possible.TimoKyyro - Wednesday, August 29, 2012 - link
I was hoping to see some GPU rendering too. I'm using CUDA on Blender and I really need more GPU power. It would be nice to know if there is a difference between 4x 680 or 2x 690 on different PCIe setups.extide - Wednesday, August 22, 2012 - link
Thanks for providing the diagrams of lane routing. I wish ALL manufacturers would supply a diagram with their boards so you know how to set it up when you are building a system. Sadly, these diagrams are the exception, not the rule. :(processinfo - Wednesday, August 22, 2012 - link
For me only EVGA seems worth consideration (I don’t like a fan on chipset though).I have few requirements that others do not meet.
I want PS/2 keyboard port (don’t care about mouse). I don’t see it as legacy. It is still superior to USB for keyboard. Works on interrupts instead of pulling, allows as many keys pressed without ghosting as you wish (know it probably does not matter in real life but I like that anyway).
Display port output is mandatory for me these days. While it is true that this kind of mobo will run dedicated graphics card (or more than one for that matter) I like to have output here for possibility to use it with CPU graphics if my graphic cards breaks and needs replacement (I had that happen and waited almost two weeks for new one). HDMI is no go because does not support high enough resolution.
Gigabyte is out for me because audio chip. Maybe it is better but it does not do 7.1 and I will lose two channels in my Tiamat 7.1 headset.

You should check out some of the newer USB keyboards. I don't know how they do it, but some of them can now do full NKRO without PS/2. My Nighthawk X9 can do full NKRO over USB.processinfo - Thursday, August 23, 2012 - link
Interesting but this is not possible with standard USB keyboard protocol. If it does that it has to use some tricks and most likely custom keyboard driver.Also I have Thermaltake Meka G1 that I like and I purchased because I got tired replacing membrane keyboards so I rather buy motherboard with PS/2 then new keyboard.
My point is that at this price point and clearly meant for gamers (who else is using more than one graphic card in non-workstation pc) they should think about such details especially when they go overboard with other ports, e.g., who needs all 4 kinds of display output on gaming mobo, or 10 USB ports on back plate alone (if you need plenty you can have them on bracket connected to header).

I loved the review. The G1.Sniper 3 was on my short list for a while. Could get back on, though.I'm waiting for the ASUS Maximus V Extreme to get tested next.
I only need a motherboard to complete my new build. I plan on running this new rig for 6+ years so I want a board that can keep up with the times.

I am staying away from the Rampage/Maximus lines from Asus this time out as Gigabyte has pretty much brought better value accross the board on their gamer boards. I don't expect Asus to catch up till the next chipset..
