Hi all,
I would like to build a Skylake system and I have a question about the PCIe lanes. The i7-6700K CPU supports maximum 16 lanes, from which the VGA uses 16 (all of them). So If I buy anything (in my case I would like to buy two PCIe M.2 SSD (Gen3 x4)) which uses PCIe lanes, then it will slow down my VGA? Or doesn't it matter if these PCIe devices connected to the PCH and not to the CPU?
Here is my MB's block diagram, but I'm not sure I fully understand it: http://kepfeltoltes.hu/151113/7977v1_www.kepfeltoltes.hu_.jpg

I don't believe that losing a couple lanes will hurt performance in any way you'll notice. The net performance increase will be drastic [imo] using a M.2 SSD

It depends on the board, but they are likely wired to the PCH on skylake.

So won't be there any performance decrease with two PCIe SSDs?
