Hey guys, I have a question.
So I'm planning on a build this summer and ran into something that I need help with.

I'm planning on running an i7 6700k, asus maximus 8 hero, gtx 1080 or 1070, ASUS Wi-Fi PCI Express Adapter, and an m.2 ssd.

Since the 6700k allows a max of 16 PCIE lanes, will that be enough for what i want to run?
Since the gpu takes up x16 and the m.2 takes up x4 and the WiFi adapter takes x1, will it cause my hardware to not perform efficiently? And also if later in the future i want to run dual gpu's?

Thanks :)

generaly the PCIE 3.0 lanes will before the x16 slots for dual gpu setups running at 8x/8x on mainstream boards. the things like M.2 and the asus wifi will runn off the pch's PCIE lanes. there is more then enough to go around..

Its plenty.

As evil said, the M.2 slots runs off the PCH PCIe lanes while the GPU runs on the CPU PCIe lanes, yes.

It'll Be alright. Even if everything ran on the CPU PCI lanes it would be something like : GPU x8PCIe lanes, m.2 x4PCI lanes, wifi adaper x1PCI lanes.
So dont worry! :)
