PCIe M.2 SSD and GPU

[TheGreatWizardCalder]

Heyo, so I'm upgrading to a 9900k and the boards only seem to support 6 SATA connections (shame).
So I thought "Hey I'll migrate my boot drive to an m.2 drive". Sounds good!

Here I am looking through the manual for the motherboard (haven't quite decided yet, but something in the 200-250ish CAD range, for the purposes of this post I looked at the manual of the Z390 MAG board from MSI) and it lists possible configs for your drive. The one I'm talking about specifically was an m.2 PCie drive w/ all 6 sata ports populated. 
What I was wondering is if the m.2 is using the PCIe does it eat into the bandwidth the GPU would normally take up?

So anyways, TL;DR: If I use an m.2 PCie slot will it take bandwidth away from my GPU? Or does it have it's own bandwidth allotment separate to that?
Thanks for any help! And if you have any motherboard recommendations I'd be glad to hear them :^)

Surprise: The M.2 slot will disable two of your SATA ports if it's used.

M.2 SSDs use PCIe lanes from the chipset, not the CPU. So no, it won't take bandwidth away from your graphics card (not that your GPU would saturate all the PCIe lanes anyways).

according to the manual the pcie M.2 keeps all 6 sata enabled. Not the same with a sata M.2 apparently. 

 

Good to know the pcie M.2 has its own lanes though.
