Dual Video Cards + M.2 SSD, constrained PCI 3.0?

Looking to purchase and build (which I haven't done for several years) The following.

ASRock X370 Taichi
Dual GTX 1080 Ti Video Cards
960 Evo M.2 1TB SSD

I'm not fully versed on the M.2, will this configuration put too much strain on the PCI 3.0 and slow down either the SSD or one of the Video cards?

  1. 1) You can find the manual here: http://asrock.pc.cdn.bitgravity.com/Manual/X370%20Taichi.pdf
    2) A motherboard can usually support full usage of all its active PCIe lanes. Designs tend to "share" lanes, for example, if you use the m.2 slot two of the SATA ports will be unavailable (random example, not from your board). A limiting factor is the bandwidth between the southbridge and the CPU in some cases.
    3) From the manual:
    " If M2_1 is occupied, PCIE4 will be disabled" and " If M2_2 is occupied, PCIE5 slot will be disabled."
    These are:
    PCIE4 (PCIe 2.0 x1 slot) is used for PCI Express x1 lane width cards.
    PCIE5 (PCIe 2.0 x16 slot) is used for PCI Express x4 lane width graphics cards.
    You should be fine, with both graphics cards running PCIe 3.0 at 8 lanes.

  2. What cpu are you considering? Also, get yourself a high quality PSU for that build.
