    Same from another post but oh well.
    Are you sure that with the i7-5820K CPU you do not get Two X16 PCIe Slots?
    And then X8 X8 X8 in 3-Way?

    With a 28 lane CPU, 5820K, you can only have one GPU @ x16 PCI, correct.  
     
    Check out the manual for the X99 FTW if you have any other questions besides that.

    Yep! Page 9
    The i7-5820K seems to be a waste if you are running 2-Way SLI in my book.
    One Card I guess it would be ok but then it would be as waste to get the Classified or even the FTW Motherboard.
    The Micro seems to be the best match up and any Duel GPU Card like the Titan Z or what ever is coming out next.

    PE4 – x16 (x8 if PE3 is used)
    PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH)
    PE6 – x8
     
    PCI-E Lane Distribution (28 Lane Processor)
    PE1 – x16 (x8 if PE2)
    PE2 – x8
    PE3 – x8 (Slot is *NOT* functional with a 28 lane processor.)
    PE4 – x8
    PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH)
    PE6 – x4

    So lets say you put:
    PE1 - GTX780.
    PE2 - Video Capture Card.
    PE3 - NOTHING. Disabled
    PE4 - RAID Card.
    PE5 - Soundblaster Z.
    PE6 - Firewire 400 card.
     
    Or in any order, except PE1 will always be GTX780.
     
    Would this cause PE1 to run @ x8
    It says if used, not if a second GPU is installed, cause none of these cards will require 12 lanes in total.
    and there are 18 lanes still available with PE1 using 16
    28-16=12 +4=18 Right?
    but I'm guessing if a card is installed in PE2 it will automatically change both slots to 8 lanes.
     
    Am I correct?
     
    Also with a 5820k you get a total of 32 lanes as the PCH supplies a x4 slot.
    thats still alot of lanes, just don't like how they are distributed..
     
    Thanks..

    Yes if you populate slot 2 it automatically sets slot 1 to x8.  Also don't be surprised if you need to manually set some of the slots.  My SB sound card I had to set to gen 1, because on auto it would not recognize it.

    Huh?  I believe and almost certain you get only 28 Lanes.  The CPU is in charge of that.
     
    When you add PCI-E cards whether its a x16 GPU to a x2 or x4 sound or raid card etc., you still use up the lanes on the CPU.  If my memory serves me correctly, the SATA part of the board, uses up PCI-E lanes as well but could be wrong.

    On this board, there are no M.2 Slots,or SATA Express Ports.
    those are provided by the PCIe on other motherboards that are equipped. ie.. X99 Classified
     
    All SATA ports are controlled by the X99 PCH, Pg. 5 of the manual.
     
    You also get 4 PCIe lanes that are controlled by the X99 PCH as well
    - "4 lanes pulled from PCH" as described in the manual  Pg. 9
    PE5 – x4 (Gen 2 only, 4 lanes pulled from PCH)
     
    So you get 32 lanes with a 28 lane CPU ie.. 5820K
    you get 44 lanes with a 40 lane ie.. 5930K
     
    The X99 Workstation Boards provide 64+ lanes with a 28 lane CPU,
    X16/X16/X16/X16 +++ with a 5820k cpu due to Dual PLX chips...
     
    The FTW was my original choice, but I changed my mind to the X99-E-WS with a 5820K,
    But my mind has changed back to the EVGA FTW, I just can't seem to leave this great company.
    I have had nothing but great experiences with EVGA products. 
    So I'm grabbing this FTW with a 5930K. I believe it will last me a while.
    I will also purchase 10yr. extended warranty, I doubt I will need it, but nice to have.

    28/CPU + 4/PCH = 32
    40/CPU + 4/PCH = 44
     
    Am I not seeing it correctly?
    You can have your PCIeX1/4 in the PE5 slot and not use the CPU lanes.

    Curious why you would have a capture card in this system? Capture cards are generally used in a second system to take the encoding load off of the main system, or to stream using a second system.

    Is this the second system and going to be recording a primary system?

    I may have answered my own question, but I am just curious is all. The rest of the stuff above is too confusing, so I am not even going to try to get into it, lol.

    That is partially wrong.  The CPU is the component that tells you how many lanes your system has to offer.  So for example, there are 28 Lane CPUs like the 5820K and 40 Lane CPUs like the 5930K and 5960x.  Every CPU generation can be different.  The MB's PCI-E are the primary care taker of those lanes and will request or require "x" amount of lanes for the required component.  Figure the lanes are like a high speed highway.  
     
    So in your example, it would look like this.
     
    28/CPU - 4 (PCI-E) = 24
    40/CPU - 4 (PCI-E) = 36
     
    That example were using is saying if you had the M.2 slot enabled with a M.2 PCI-E x4 storage drive on the EVGA X99 Classified MB.
     
    If you were to add GPUs, well those depending on the speed (x8/x16) would subtract from the leftover lanes.
     
    Hope this makes sense.

    CPU PCIe controller is 3.0 while the southbridge has PCIe 2.0 controllers; can't mix them together especially when SLI doesn't enable in less than x8 electrical anyway (an nVidia artificial restriction).  You would need a board with a bridge chipset (PLX) to force the cards to run a higher electrical signal in a lower lane slot.  

    For instance, if you used a 4-way SLI LGA1150 board, those processors only have 16 lanes with their controllers, so it would split up to four x4 slots which won't work with SLI.  Throw in a bridge chipset and it tells each card to run at x16 or x8 despite the slot not being able to receive more.  Is running a modern high-end card in a 4-lane slot a bottleneck?  Not really, but then who purchases four cards and only gets a mainstream board to unlock a quad-core?  Not many.

    For Intel processors, 0.122 x TDP = Continuous Amps at 12v [source].

    The capture card is not for streaming, it is for recording from external source, EX: DVR/PVR Video Camera, VHS etc....
    I did try an Avermedia HD card with passthrough, but I could not record using native 1920x1200 monitors, even setting to 1080p was not supported..
    it would only work with 1080P native resolution.
     
    As far as the extra 4 lanes, yes you can add in an Audio card or something and not use up the CPU lanes..
    I guess this was misunderstood... I will use the PE5 slot for my Firewire Card so I don't use the CPU lanes....
    And I did have my eye on the ASUS X99-E-WS with dual PLX chips.
     
    Anyway I got this board today, and the 5930K. everything posted and is working fine,
    I am writing this from the PC now.
    It came with BIOS v112, and updated to 116 on Chip #2.
    so far just the GPU, hav'nt put in the Firewire card, or Sound blaster z yet.
