Just a short query
I want to place my PCI Express X1 Sound Card on PCI E X4 because all other slots are populated by the gigantic 1060 Hercules.

So would placing X1 Sound card lower the bandwidth of the 1st PCI E X16 Card to any lower? i.e X8 or X4? and would there be any performance bottlenecks thereby or not?

Thanks
 
Solution
If only x16, x4 on board, then yes, by placing a card in the second slot it would set the first one to x8, but you would not notice any loss.

Thanks. Just as I estimated.
What is the break-even point for the initiation of difference?
GTX 1070 or 1080 or 1080Ti
