I'm building my first computer and have received a majority of my parts. I noticed that my geforce gtx-770 will cover my pci-e x 1 slot and I want to install a wifi card. I know that I can put it in a x8 or x4 slot but will it cause my graphics card to run at x8? I will be using a gigabyte z97MX - gaming 5 mobo and a i5-4670k CPU. Thanks in advance for any help.

No. The bus will only use the x1 connections of the wifi card and let the rest of the channels remain down.

Well I got everything built and installed. Unfortunately CPU-Z says that my graphics card is running at x8 instead of x16 with the wireless card in there. I guess it's not that big of a deal, I'm sure the performance wont take that big of a hit. Just is a shame its not running at would it could be. Thanks for the answer though.

Have you got the wifi card in the middle or bottom slot? Plug it into the bottom slot, as it appears to be a 2.0 x16 slot (limited to x4 lanes) as opposed to a 3.0 x16 slot, so is wired to the chipset rather than the CPU. This means that using it should leave the full 16 lanes from the CPU available for the graphics card.
