CPU lanes questions

[Blazz]

Hi all!

 

I have a question regarding CPU lanes and how they effect in general. So I have build myself a PC and in the future I see me adding an WI-FI card to the system ( for enabling wi-fi threw connectify., or conneting to the web by wi-fi...). Now I did some research and found out that my CPU (i5 4460) supports 16 lanes and that my motherboard MSI z87 g43 gaming has the appropriate PCI express for my graphic card MSI R9 280 gaming 3g which is PCI express 3.0 16x. Now I looked for some wi fi cards and found some that work with an PCI slot and/or PCI express slot.

 

And now the questions.

If I put an wi fi card in the system lets say it works on 1x or 2x does this mean that my graphics card wil now work on 8x?

And if it will, what kind of effect will this have on the performance of the graphics card? 

Or if the wi fi card connects threw the PCI slot 1x and the graphics card is in the PCIe 16x 3.0 will it work on 16 x regardless?

The PCIe x1 slots get their lanes from the Z87/Z97 chipset and don't affect GPU performance at all.

^This.

 

16 PCIe 3.0 lanes from CPU plus 8 PCIe 2.0 lanes from the chipset. As has been explained numerous times before.
