M.2 - Pcie Lanes- GTX 1080 SLI

[Gfields2020]

Hello everyone,

Before I ask my noob question, please excuse any lack of knowledge.

Few questions that I can't seem to get a straight answer on, as I am educating myself in the realm of PCIE lanes.

To my understanding, PCIE lanes are the "roads" that your attached devices use to communicate with your processor. More lanes, more communication, I think.

Questions:

Do the GTX 1080's in SLI work best at 16x or x16, (each lane speed) lol

If so, is it true that my I7-6700k is a bottleneck, since it ONLY has 16 lanes? What processor do you recommend under $500 that has at least 40 lanes?

Do the USB, additional HDDS, and blue ray drives take up PCI lanes to the processor?

My ssd boot drive is full, so I'm going to go with a PCIE m.2, to get past the 545MB transfer speed of the Sata cable, and get to the gig speed of the PCIE slots. Won't this use lanes as well?

Thoughts on my current MOBO?

Current Specs:
I7 6700K
Maximus hero viii z170 chipset
32GB gskill ram
256 boot ssd on Sata
2TB storage on Sata
GTX 1080 #1 in SLI
GTX 1080 #2 in SLI
Blue ray read writer #1
Blue ray read writer #2
Windows 10 -64 Bit.

Thank you soo much in advance

You're right. Looks fine to me. When you SLI cards they'll run at x8/x8 which is more than enough. 16 lanes will go to the PCIe and 20 to the PCH controller. SLI'd 1080's with a m.2 drive will work out great.

check your boards manual to see if the M2 will share any cpu pci-e lanes or disable any slots you may find adding the M2 will cut the lanes to 8x4x4 and then your not NVidia SLI capable anymore

even with a 20 lane cpu there still limitations involved and how the boards pci lanes are ''wired ''

Thanks a lot, do you know a lot about MOBO's? What would be a good upgrade?
