Multi-GPU Setups
The Gigabyte Z77X-UD5H is the first Z77 motherboard we have tested that uses a full PCIe 3.0 tri-GPU setup, such that we have:
One GPU: x16
Two GPUs: x8/x8
Three GPUs: x8/x4/x4
Our other comparison points use four PCIe 2.0 lanes from the chipset. These setups suffer from limited bandwidth on the third GPU, as well as additional latency as data must transfer through the chipset. These motherboards have a setup such that:
One GPU: x16
Two GPUs: x8/x8
Three GPUs x8/x8/PCIe 2.0 x4
In our testing, we show that the first method of PCIe layout performs a lot better in tri-GPU setups. Note that the downside of this is that if a Z77 motherboard is paired with a non PCIe 3.0 CPU (such as Sandy Bridge), then the final PCIe slot on the board is not functional.
Civilization V
Civilization V is a strategy video game that utilizes a significant number of the latest GPU features and software advances. Using the in-game benchmark, we run Civilization V at 2560x1440 with full graphical settings, similar to Ryan in his GPU testing functionality. Results reported by the benchmark are the total number of frames in sixty seconds, which we normalize to frames per second.
While the UD5H does not perform the best in single and dual AMD cards in Civilization V, it does take the top spot against our tri-AMD setup.
For whatever reason our single NVIDIA test does not perform that well, but the dual NVIDIA GPU test comes near the top.
Dirt 3
Dirt 3 is a rallying video game and the third in the Dirt series of the Colin McRae Rally series, developed and published by Codemasters. Using the in game benchmark, Dirt 3 is run at 2560x1440 with full graphical settings. Results are reported as the average frame rate across four runs.
While in the single AMD Dirt3 test the Z77X-UD5H comes bottom, all the results are within statistical variance. In comparison, in the dual AMD Dirt3 test the Z77X-UD5H comes near the top. In our tri-GPU test, the full PCIe 3.0 x4 of the Z77X-UD5H shows its worth with an extra 35-40 FPS over our other motherboards tested.
In both our Dirt3 NVIDIA tests, the Z77X-UD5H performs well but within statistical variance of every other board tested.
Metro2033
Metro2033 is a DX11 benchmark that challenges every system that tries to run it at any high-end settings. Developed by 4A Games and released in March 2010, we use the inbuilt DirectX 11 Frontline benchmark to test the hardware at 2560x1440 with full graphical settings. Results are given as the average frame rate from 10 runs.
On our Metro 2033 tests, the full PCIe 3.0 functionality of the third GPU shows again, with the Z77X-UD5H performing another 5% better than the Biostar.
Our NVIDIA testing in Metro 2033 shows every board performing almost the same.

Derp. Well, color me stupid.Nice one, though. ;)

Okay, you are stupid.Well, for another reason. Nobody makes a keyboard worthwhile to replace the one I use today... 1996 era. This keyboard *IS SO OLD*, its not even a PS/2! Its an AT-connector, plugged into a PS/2 3" Adapter into an extended PS/2 cable. A USB convert doesn't work.
But gigabyte makes many boards with ps/2 ports.
VGA is not needed on a high end board (lower end $60~120 boards have VGA).
And actually, a floppy connector *IS NOT* needed of modern boards. When a modern board like Gigabyte doesn't include a floppy connector, they can update the BIOS from within the OS or with a flash drive.... far easier than a stupid old-school floppy drive (I keep one just in case).

Did you test the VIA USB 3 chip performance, or only the Intel PCH controller?Mustang66 - Wednesday, July 25, 2012 - link
Are the two red USB ports on the back 2.0 or 3.0? The paragraph says they're 3.0 but the feature list seems to infer they are 2.0.IanCutress - Wednesday, July 25, 2012 - link
Sorry, the red ones are USB 2.0. USB 3.0 on every manufacturer is currently blue (for now).Ian

No Dual link DVI Port on HD4000, so I can't run my old 30" display without dedicated card.Craxit - Wednesday, July 25, 2012 - link
Display-Port to DVI-D cable?Same prob here.

So Gigabyte finally dropped VIA as the onboard audio provider on their motherboards. About time- I almost swore off Gigabyte because I had so much trouble with that driver!rickon66 - Wednesday, July 25, 2012 - link
I have this board and really like it. The board package includes a front panel USB 3 bracket so you can add USB3 to the front of your case. I thought that was a very nice addition. The board is built so stoutly that it could double as body armor.Craxit - Wednesday, July 25, 2012 - link
Has anybody found out how to switch on the boardby keyboard?
Can do wakeup from sleep using the kbd but not a cold start.
