M.2 ssd shares bandwidth with graphics card?

Not really, we just said it differently. Your cpu has 16x lanes that are used for the pcie slot (basicly), while the chipset has 20x lanes for aditional bandwith. If you plug the m.2 in a pcie slot it will put your card in 8x, but even if it does it isnt a concern since there is no preformance difference.If you put the m.2 ssd in the m.2 slot in the motherboard your card should still run in 16x
And no, you cant just upgrade the no. of cpu lanes with drivers.

The z170 board have 20 lanes connected to the chipset and 16 lanes with the cpu, so the m.2 should be connecting with the chipset, not taking away any bandwith from the card, if you have all the chipset lanes used up then it could put your gpu in 8x, but that will not affect you graphics card preformance anyway.

Actually I understand now thanks gingerbread, will Skylake have support for more then 16 lanes in the future? And if it does will it just be a matter of a driver update or will I need to upgrade my cpu?
