Thats the reason I didnt purchase an X99 no one had an add on NVME raid controller out yet and it wasnt supported at all on X99. Z270 is bandwidth limited by the 4 lanes used by DMI, so I was hoping either x299 or amd x399 would address this massive bottleneck in the new generation. But I havent see it addressed on either platform. I saw one snippet that suggested it was IRST supported on an Asus board which suggest its still a bottleneck.
 
If it is I'll buy one of the new add on raid controllers with the 4 M.2 slots in it and run an X399 platform with two graphics cards.

This link also gives a very concise diagram of the problem.

Whoo Hoo about the X299 Micro board.. I was concerned if EVGA was canceling out the Micro boards.. I am now running X99 Micro.. I am curious though what CPU socket will it be running on? 

Intel X299 chipset will not only be replacing the X99 chipset, but it would also introduce a new socket. The new socket will be required to support Kaby Lake-X and Skylake-X processors. We have known this socket as LGA 2066. The name reveals that the socket will feature exactly 2066 pins. This is an increase of 55 pins from the previous socket. Since Skylake is architecturally different than Haswell and Broadwell, it was necessary to make the shift. Link
 
The new socket will span at least three generations of processors, Skylake, Kaby Lake and Cannonlake. Intel will only need to update it when they introduce their Ice Lake architecture based processors which would be around 2020. That new socket would be known as LGA 2076, more details on that here.

BCAVNAUGH- Many Thanks for the detailed specs... I appreciate it!

Thank you for sharing this info.  I want to be informed about my big move from Bloomfield to Skylake-X and spend that coin wisely.

So kabylake x get dual channel ram and 16 pcie lanes and skylake x get quad channel and 28 lanes and the big dog 12+ get 44 pcie lanes. Bit confusing intel.

I look at this way; one for Gamers Only and the other for users that Game sometime but are Folders and Crunchers at heart.
The really Big Picture is what is Dell and HP doing for CPU's as in the current state I think both use substandard CPUs or very low grade CPUs in their Desktop Computers.

Really like all three and am excited about the new chips from Intel. Still not really sold on the RGB lighting but could get used to it.

Go with the Dark or wait to see what the Classified comes with.

The 10 core 7900x gets 44 pci-e lanes as well.

My bad, i missed that one. But still i dont get the kabylake thing, they took a 1151 cpu, disabled the intel video and stuck it on a 2066 board. If going to HEDT platform why would you want basically a z270 spec system, the x299 still only has 24 pcie lanes so were is the benefit other than the ability to upgrade the cpu later on?

Can someone explain if I need more than 16 pcie lanes for two 1080 ti's and two M.2 sdds. I know the cards must run at 8x

Each 1080 TI would want 16 lanes.  Most m.2 are x4 so there is another 8...for everything to run full...you would need 40 lanes.  Right now...both 1080 TI's would run x8 and m.2 at full

If you plug in the m.2 on the motherboard then it takes/shares the lanes for some of the sata ports.  If you use a PCIe card then it takes it from the lanes that's listed on the CPU.  Sata port PCI lanes are normally not listed on the CPU because it will be used out of the bat.  It really depends on the motherboard implementation so hard to say without motherboard specs because they can add chips to add lanes and feed all lanes to the CPU lanes.  Example chips can have 100 lanes total and CPU has 40 lanes.  the chips will talk to the 40 CPU lanes but handle the communications from all 100 lanes that devices connect to on the PCI lanes chips.  They used to call these chips PLEX I believe.
 
As a side note I don't think you will be missing out on a whole lot if your 1080 ti are running on 4 lanes each, I'm sure this will open up a whole slew of discussions though.  Normally motherboards are programable to indicate how many lanes it will provide per PCI slot if you wanted to set them to 4x for example.

Again, that's only if the m.2 slots use PCI-e lanes from the chipset. With X299 having 44 CPU PCI-e lanes, there is plenty of room for the m.2 slots to be on the CPU lanes. Like I said above, we'll have to wait to see the spec sheets and manuals for these boards to be sure, but I don't think (I hope!) manufacturers would put the m.2 slots through the chipset with so many CPU lanes available. The Z270 boards did this because they only had 16 CPU lanes available, so the m.2 HAD to go through the chipset.
 
You will most definitely be missing out if you run graphics cards in x4, especially 1080 Tis!! Graphics cards can be run on x8 just fine without bottleneck; no card needs all x16 lanes. x4 however will severely limit your graphics card; in fact, I don't think it can run in x4, only x8 or x16, though someone else may know better.

I just seen a post of tests that x8 vs 16x on a titan x pascal was losing only around 2% with a single card and basically no difference when using SLI.

The next question is will the classified X299 boards come out with PCIE 4.0?

Enjoy life in the slow lane. Small cpu's can't be soldered because it shortens their lifespan. No problem with that on x399 since the quad quad cpu is the size of a credit card.

My only real questions at this point are when will these be up for sale and for how much?
I'm likely parting out my current build and selling it off to move to X299 and I'd love to consider the Dark, but I need to go with something that corresponds with CPU launch and price does matter.
 
I'd also like confirmation that the two released MOBO's will fit in the DG7 cases (as those list only ATX and not E-ATX compat).

Getting a 6core for $220. And pairing it with a $100 motherboard Intel refuses to offer a six-core CPU at what I would call a reasonable price.

 
Please do let us know more about this EVGA X299 Motherboard for only One Hundred Dollars.
Being that this Thread is about EVGA X299 Motherboards coming soon.

jchambers2586
There is no because Intel refuses to compete with AMD

Maybe you have this Backwards.
But we need to get back on Topic "EVGA X299 Motherboards [coming soon]" and not AMD and Intel's Politics.
