Alright so, I'm building a PC with the following main components: (minus an I7 6700K ofcourse)
ASRock Z170 Extreme7+ LGA 1151 Intel Z170 HDMI SATA 6Gb/s USB 3.1 USB 3.0 ATX Intel Motherboard

SAMSUNG 950 PRO M.2 512GB PCI-Express 3.0 x4 Internal Solid State Drive (SSD) MZ-V5P512BW

GIGABYTE GeForce GTX 980Ti 6GB WINDFORCE 3X OC EDITION
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125803&cm_re=gigabyte_980Ti-_-14-125-803-_-Product
and I already have this sound card from my old build:
Creative Sound Blaster ZxR PCIe 124dB SNR Sound Card with 600ohm Headphone Amp and Desktop Audio Control Module

Now comes my question. If I want to go with either 1 graphics card (PCIe 3.0 x16 lanes) or 2 graphics card (8x/8x) and the Samsung SSD would take 4 lanes, would the amount of PCI lanes (20 for the 6700K) be sufficient for this build? or would the card(s) have to run in an x4 setup due to the lack of availability of PCI lanes?
