Packed with four extra USB 3.0 ports and two eSATA connectors, Gigabyte put great effort into locking the Z87X-UD3H at its current $160 price point. The board's I/O panel is similarly packed with four full-sized video connectors, though the CPU’s integrated controller only supports three simultaneous outputs.
The six I/O panel-based USB 3.0 ports are easily accessed, but the same convenience doesn’t always apply to the Z87X-UD3H’s four front-panel connectors. That’s because one of the dual-port headers is located beneath the bottom PCIe x16 slot, where it can be blocked by a graphics card.
Not that most of us would put a graphics card in the third slot. The top two x16 slots share the processor’s sixteen PCIe 3.0 pathways, switching from x16/x0 to x8/x8 whenever the second slot is filled. Meanwhile, the bottom slot gets its four lanes from the Platform Controller Hub. Furthermore, placing a x4 (or longer) card in the bottom slot causes the Z87X-UD3H to disable two of its x1 slots.
The x1 slots that get disabled are located between the first and second x16 slots. This makes sense, since the first slot under a graphics card is often blocked by a graphics cooler anyway. At least Gigabyte was thoughtful enough to make the top x1 slot always active.
The Z87X-UD3H encourages overclocking exhibitions with its placement of power, reset, and CLR_CMOS buttons in the board’s upper-front corner. A pair of CMOS selector switches next to those buttons lets you jump from one IC to the other, and disable dual-BIOS technology to prevent improper error recovery. The exhibition theme continues, bolstered by a row of voltage detection points along the front edge. Gigabyte even adds a Port 80 code display next to the main power connector to tell overly-aggressive overclockers what they did wrong.
Traditionally, front-panel audio connectors show up in the bottom-rear corner, and Gigabyte lets history repeat itself on its Z87X-UD3H. Unfortunately, the front-panel cables on some cases are just a little too short to reach. Builders who like to wrap their auxiliary +12 V power cable over the top of the motherboard tray will also find the eight-pin connector's upward-facing latch difficult to disengage once the cable is wrapped tightly over it.
Apart from those minor differences, the Z87X-UD3H layout resembles the first three motherboards that we've already outlined in this round-up. Three slots worth of spacing between x16 interfaces improves airflow in systems with multiple graphics cards, and forward-facing SATA connectors work with all but the most outdated case designs.

The Z87X-UD3H includes only four SATA cables to connect its eight internal ports. Of course, you could instead pretend that the board only has six internal ports, since two must remain unpopulated in order to enable eSATA.

1- the x8x4x4 PCIe controller is a CPU feature in all i5 and i7. All the z*7 chipset does is unlock the CPU feature
2- same goes for multipliers on K-chips: CPU feature locked out by non-z*7 chipsets
3- SATA-6G ports do not really cost Intel any thing extra to put on-chip (little more than a PLL tweak to lock on faster signals), which makes it somewhat of a shame they aren't fully standard
4- USB3 ports do not cost Intel all that much extra either - maybe an extra square millimeter on silicon to upgrade all remaining USB2 ports to USB3
5- the DMI bus can only manage ~20Gbps so it will bottleneck if you attempt to use even 1/5th the total the connectivity available on z87
More connectivity, yes. But DMI lacks the muscle to actually stress that extra IO. As such, it is little more than a glorified SATA port replicator and USB hub.
I almost exclusively use Intel CPUs but it still annoys me how Intel charges extra for trivial things or unlock stuff they arbitrarily locked out just because they can.

In other words, they might be charging for stuff that should be free or should have been included all the way back in the Z68, but past omission doesn't negate current usefullness.
The market is flooded with tons of these Z87 motherboards and it can be very overwhelming researching them. So, hopefully we'll see a few more Z87 reviews from you guys, soon.
Would also like to see some powerful i7 builds built around more energy efficient components. That would be very interesting. Hint.
Rather surprised that Biostar had such a good board. Maybe it's time to start considering those boards for future builds.
It is great to see a round-up of the mainstream boards, though, so thanks!
Most users don't have enough such devices to fill every port in the first place (how many people need more than two upper-tier SSDs?) but those who might actually "need" and use 6xSATA-6G would be people wanting to do things like RAID0/1/5 with 3-6x SSDs. At 6x SSDs, we would be looking at ~25Gbps peak not counting GbE, USB3 or PCIe devices on the 8x 2.0 lanes.
Still does not change the fact that the only reason why Intel gets away with charging $10-15 extra for less than $1 worth of features while the DMI bus lacks the bandwidth to properly support them for people who may actually intend to use them is because they have a practical monopoly which allows them to arbitrarily fragment the market so they can artificially inflate prices.
The main reason most people go with z?7 is the overclock unlock for K-chips. That itself is the biggest joke since it is a completely artificial limitation Intel engineered into their products to enforce co-upselling. As shown with the h87 slip-up, the h87 is perfectly capable of managing multipliers on Haswell K-chips when the K-chip lacks the microcode to enforce the z87 unlock "requirement."
I don't bother with overclocking so this does not affect me... but it still annoys me on the basis of principles and general dislike for hair-splitting for profit.
I'm about to build a new gaming box, and I'll consider the 'winners' in the article when I'm shopping. While price is not a big driver for me, I'll see if ASRock stays true.
Instead of just cheap, you mean?
ASUS - 16
ASRock - 10
Gigabyte - 11
MSI - 8
ECS - 3
Biostar - 2
How in the heck does marketing sort out product definition for 16 models, all for the same form factor?
ANYWAY, your choice
Spend a lot for a single issue fix
Spend a lot more for a new layout with superior everything and future proof for next gen CPUs.
Spend nothing, stop whining and deal with it.
Thanks
