Can someone verify if one of the PCIe slots will have 16x for a single 1080 Ti if using a i7-7740X in the EVGA X299 FTW K? If it's only 8x for a 16 lane CPU...I might get one of the other available mainboards that are out now. I see some boards have 16x available for a single GPU + 16 lane CPU and some only have 8x.
I know that 8x vs 16x on a single GPU isn't a significant difference but it leaves a bad taste in my mouth.

Welcome to the Forum Kantankerus As with all of us we have to wait for the Release of this Product for this information. Going X299 Dark Next Spring myself.

you dont need pci-e palnes for gaming, there was alot of testing between 44 and 16 lane cpus and the preformance is the same, even with SLI

It's debatable. Some testing shows no difference or very insignificant. Some shows up to 30% difference in SLI x8/x8 vs x16/x16. Overall, it seems like there is _some_ difference in _some_ software, but often not enough to worry about.
On the other hand, if the two X299 boards cost roughly the same and have roughly the same features, there's no harm in wanting one that maximizes performance, even it's it's "1% in that one game".
Then again...I've already decided, for ME, that the i7-7740X is an interim CPU until something truly better comes along for MY needs, so in that light..I probably shouldn't fret...but to fret is to be human. :D

If I am going to use 2 Cards I would NOT waste my money on a CPU or Motherboard to only to have them run at x8/x8 or even x16/x8. Computers do more than just Game is all I am saying in the Scheme of Things. X16/X16 or Nothing, X16/X16/X8 is Cool.

Good luck using 960PRO SSDs with 16 pci-e lanes if you already use two videocards in multigpu configuration.

depending on which slots are tied to the cpu lanes and if any other devices are like m.2 slots, with using such a wide range of cpu's it will depend on what you pick. im thinking intel's thought is for a gaming/enthusiast setup that people will choose a higher level cpu and stay away from the kaby lake x ones, which makes sense.

I can, I have 44 lane CPU Also I have two NVMe drives But for regular person x8 for GPU and x4 for NVMe and performance is the same - well, in games :)

PE2 is x16, if PE5 is populated then they both operate at x8. PE3/4 are no functional with 16 lane processors, PE1/6 pull lanes from PCH.

Thanks EVGATech_DaveB! After seeing der8auer lambast the initial round of X299 boards because of poor VRM design/cooling I'm thinking that waiting for EVGA with their enticing VRM designs on their X299 boards is an even better plan than I originally thought. Will definitely be waiting at this time, if not just for the added support touch. Much appreciate the pre-launch information!

It seems like most of the boards (not all) are tying M.2 slots to the chipset PCIe lanes and not CPU, no? I know I saw at least one tying at least one M.2 slot to CPU lanes but I think the majority I looked at are not. Correct me if I'm wrong.

Some boards but not all, there is a mix between CPU and PCH lanes for M.2 devices. The manuals have been posted, and there is full PCIE lane breakdowns, per CPU type (44/28/16 lane variants) for slot as well as M.2/U.2 etc allocation. The breakdowns are in the 23 on the Micro, and 24/25 on the FTW if memory serves.

@EVGATech_DaveB Thanks for the additional information.
From the manual for X299 FTW K, it looks like 16-lane CPUs (like i7-7740X) will only have x8 CPU lanes for PE2. Even if that's not the case with a single GPU, it looks like with two M.2 devices (one in 110mm M.2 slot and one in the 80mm M.2 slot) I'll definitely be at x8 CPU lanes for PE2 at that point. Is this correct? Not the end of the world...it seems things are messier regarding lane allocation than I could have imagined. Must have been a PITA for the board engineers...amplified by the rushed schedule, I'm sure.
At least EVGA spells out what is using CPU and what is using PCH. That info seems nowhere to be found in the Asus manual, for example, at least that I could see.

With a 16 lane proc, PE2 is x8 only. Other 8 lanes go to PE5, and those are shared with the larger M.2, and the 80mm M.2 is PCH only so that will not be effected in any way.
Having 3 different lane counts from CPUs does make this interesting to say the least, if it looks a little convoluted from the manual side, you should see the back end of it, the schematic can make you O.o at first glance.
I felt the lane breakdowns are important, the more you know about how it works the better you can plan for whatever it is you want to do there. IMHO, unless something really left field happens, the manual should have everything you need to know to resolve/understand something without needing customer service, and I wrote the manual with that intention.

I think I comprehend the manual at this point and everything is clear. I don't envy the task of figuring out the syntax for the manuals for any of the X299 boards...someone probably will come out with an interactive web interface for determining what you get if you plug in which component where.  I honestly can't comprehend the insanity on the back end...I'm guessing there were some near nervous breakdowns when engineers tried to wrap their brains around that, and I sure a few choice words uttered. I totally agree on the inclusion of the detailed lane information in the manual and it is greatly appreciated. Thanks again!

This might be off topic but will there be a way to disable the RGB lighting on this board. IMO it's God awfully ugly on this board

from the look of the pcie lanes if using a kaby lake cpu you only get x8 for one gpu since the 110mm m.2 pulls 4 lanes from the cpu. intel really made things interesting with this.
