Need some advice regarding PCIe lanes?

Hi guys,

I'm looking at getting an Aqua Computer M.2 PCIe 3.0 x4 adapter card for my Samsung 960 Pro M.2 NVMe SSD to use in my Asus Crosshair VI Extreme motherboard and I'm concerned that the only slot that will give the full PCIe 3.0 x4 bandwidth is shared with my GPU (GTX 1080).

(I'm using a Ryzen 7 1800X CPU)

Here is the relevant page from the Asus manual:

Here is the Aqua Computer adapter card:

Here is the Samsung M.2 NVMe SSD:

So will I lose half the bandwidth to my GPU if I use the other PCIe 3.0 socket or is it only reduced if I use a 2nd GPU?

Will I loose a lot of bandwidth if the SSD had to go in a PCIe 2.0 lane?

Good idea, gives me another option, I'll likely use this as I'll probably not notice a slight drop in the NVMe speeds but I want all me frames with my 1080, especially considering how much frames cost these days :P
