I am moving to a i7 6700k with a 980ti on a mini itx board, therefore it has only one GPU slot. The mother bd has a m2 SSD slot, so i was thinking of utilising that but i am concerned that it may rob my 3.0 x 16 capability and reduce it to 3.0 x 8. Can anyone give me advice.
From what I think I've found out, using M2 SSD slot will make the Gen 3 PCIe x 16. drop to Gen 3 PCIe x 8. If I have missed some forum update chat about this; rfactor2 performs at at approximately 15% lower frame rates. again I am not sure if later builds have countered this. If this is not correct please chime in and have your say.
Hopefully reading this page may help you work it out. https://www.reddit.com/r/buildapc/comments/3fz4s7/skylake_6700k_z170_and_pcie_lanes/
