The reduction in speed is relevant to the chipset and CPU. If you go with X299 the DIMM.2 will not slow down the PCIe speed to 8x with the right CPU because you will have ample PCIe lanes.
With my setup, I have dual DIMM.2 cards and a total of 4 NVMe drives (2 on each DIMM.2) and the GPU still runs at full bore 16x.

Dear Mr. Fox!
Would you please tell me, that configuration do you use?
I'm confused a bit and would appreciate any help. I would like to build a new rig, using at least 2 pieces of 970 EVO M.2. This SSD has a maximum read speed of 3500 MB/s. If I buy Maximus XI Formula or Extreme +9900K, I can't use the two M.2 drives in a PCIe slot (with a PCIe card or DIMM.2), becouse I will not want to have X8 bandwidth for my graphics card instead of X16 (I know, the difference is marginal, but with new RTX cards there actually will be some FPS difference). If I insert the two M.2 SSDs into the onboard slots, than I will be bottlenecked by the chipset, becouse DMI bus will allow only 3,9 GB*s in total. So, another choice could be an Asus Rampage Deluxe II + 9900X. In this case, I would have enough PCIe lanes for all my M.2 cards to run at full speed + X16 for my video card. But X processors haveless boost speeds than for example 9900K (5Ghz on two cores or overclocked to all). So perhaps X processors are not as effective for games as 9900K (?). But here comes another dilemma. If I use two M.2 SSDs on the board slots and not raiding them, would the DMI bus speed really matter that much in reality? For example when copying files from one drive to another?
Thanks!

I was looking for a definitive answer to this lane allocation question on the M11E too. If I use the dimm.2 with one SSD that still might decrease the graphics card to 8x, but is there a bios setting to switch the dimm.2 to the PCH? The top and bottom slots on the board are not connected to the CPU so I could use an adapter in the very top slot and run the SSD via the PCH. Anyone know for sure?

I'm also looking for a clear answer to this. If I have one M.2 in the Dimm.2 riser card how can I still retain the PCIE at 16x?
