The P9X79 Pro offers buyers a less-costly alternative to Asus' Deluxe board by dropping a few features that many enthusiasts won’t even notice. Notably missing are Wi-Fi and the twin Ethernet controllers, while Bluetooth, dual eSATA, and quad rear-panel USB 3.0 ports are retained.
Ubiquitous on its enthusiast-level products, Asus' USB BIOS Flashback feature allows a BIOS update without so much as a CPU installed. In fact, even this board's slot arrangement is carried over from the more-costly Deluxe platform.
That means three-way SLI is still configurable using double-slot cards within a seven-slot case, but without any extra space between the top and middle cards to improve GPU cooling. Asus places all front-panel headers above or below this card space to avoid any fitment issues, and the company points its eight SATA ports forward for the same reason.
Asus’ TPU switch still enables one of its overclocking profiles. The EPU switch still enables one of its power-saving profiles. And the MemOK button can still be used to underclock RAM below its SPD profile, just in case you end up with poorly-programmed memory.
Overclockers will love the Port 80 diagnostics display, while bench testers will take advantage of on+board power and reset buttons. Both will likely favor the CLR_CMOS button as well, which is cleverly hidden between a USB 2.0 header and fan port along the motherboard’s bottom edge.
With no serious complaints to voice over Asus’ layout, we can still point out that Asus is the only company not implementing Intel’s standard arrangement for front-panel power, reset, and LED pins. In fact, Asus may be the reason why so many cases have split power LED connectors, why some cases have those same pins three spaces apart (in AT-form-factor-fashion) rather than adjacent to each other, and why no case manufacturer has yet switched to a single-piece standard for the eight associated wires.

Asus includes six SATA cables, three-way and two-way SLI bridges, and front-panel quick connectors in its P9X79 Pro installation kit. CrossFire users should find the appropriate bridge cables included with their cards, though you'll probably find them to be too short to bridge between this board's 16-lane slots. Because of this design decision, we would have liked to see a long CrossFire bridge (similar to the included two-way SLI bridge) come bundled with this kit.

ASRock X79 Extreme6/GB - very nice all black looks better than gigabytes atempt
Asus P9X79 Pro - new baby blue they use on all the boards... not for me
ECS X79R-AX - looks like my old pentium 2 board with the white slots
Foxconn Quantumian-1 - i like i like gives a feeling of the ROG ASUS boards
Gigabyte X79-UD3 - rip of from the ASRock X79 Extreme6/GB (lol) plus the southbridge heatsink looks old fasion and ugly.
Intel DX79SI - now this board for me looks good actualy more than good looks the best
MSI X79A-GD65 8D - also very nice love the blue + Black.
If you have one of the boards and i insulted it, wasnt the intention, just my view of the board>
One thing I'm not sure of is the acceptance and actual usage of eSATA. While practical at some level, is anyone actually using this MB feature or is this one of those things the MB producers can skip out on like parallel and serial ports? I'm not sure enthusiasts are all that into using their eSATA ports?
Personally, I think this is one of those money saving opportunities MB producers should consider.
Here -- where? You guy's may have gotten an early release, but how's that been working far? The official re-release is January 20th to retail. The reason I state this is because the track record has been less than stellar and in some cases often a 'miss-match' the the retail versions; thereby (WE) get ambiguous impressions and folks buying habits are incorrectly forged.
From the results I've seen, read so far, a ±2FPS~±3FPS can all fall within the margins of error; run the tests 3-4 times.
Then the reasons for 'choices' as 'best', IMO best must have 8xDIMM, 3-WAY, decent audio, good OC'ing, and adequate plus fast SATA ports. Asus P9X79 Pro and Intel Intel DX79SI, while I appreciate a budget 4-WAY Gigabyte GA-X79-UD3 no one wanting 4-WAY is going to choose it.
- my 2 cents.
When will AMD be coming out with mobos with PCIe 3 support?

My D975XBX board is still holding strong after like 6+ years of owning it. It's currently sitting in my HTPC.
I'd definitely go for the Intel for that reason alone, but I've been really impressed with Gigabyte and the way my Z68 system turned out.
1. Not much better, I decided not to mothball my 980X and instead to only replace my GPU's with GTX 600 series when available and then with 3GB vRAM.
2. Not much with clock-to-clock comparison; e.g. 4.5GHz to 4.5GHz. Sure the SB/SB-E is slightly faster but in most resolutions none of them really impede or bottleneck.
3. (link) well it seems I was right PCIe 2.x versus PCIe 3.x -> http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/49646-amd-radeon-hd-7970-3gb-review-21.html the GPU's cannot saturate x8 PCIe 2.x so it will be quite a while if not years before PCIe 3.x gains ground to make it useful.
Nice review though and I understand how both of these things were outside the scope of what was being done.
I see what you're saying, but during BF3 my good trusty ole i7-960 and my two GTX580s are all hitting 100% at times (until BF4) running on ultra with AA and AA transparency cranked. I'm getting over 100fps at 1080p. I'd say that's a good equipment pairing considering I'm going on year three. If that's what an anal pounding is all about... Thank you sir may I have another!?
