Hi guys

I shall be either building or buying an x299 Intel Skylake system soon and I've hit a wall in trying to comprehend the issue of Lanes. The system will be something similar to this:

Intel Core i9-7900X 10 Core Skylake - 44 lanes OR i7-7820X 8 Core Skylake - 28 lanes
ASUS ROG Rampage VI Extreme motherboard OR ASUS ROG Rampage VI Apex (I'm open to other suggestions)
32GB Corsair Vengeance RGB Pro 3000Mhz RAM
I already have an nVidia GTX 1080Ti and I will not go down the SLI route
I already have x2 M.2 drives and 3 regular SSDs
Phanteks Evolv X

However, it's possible I will get another M.2 drive so I'll have 3 in total but I don't know where that will leave me with regard to Lanes or whether I shouldn't worry about it or what. If you can help or point me in the direction of a good online article that would be much appreciated.

Any comments or views would be VERY welcome! Thank you.
