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.
