I was looking up on what I would need to install for a wireless desktop and it seemed that the pci, pci-e, or a usb card. I use my rig for gaming so connection is important to me so pci-e seemed to be the way to go, but upon further research I can't really find anywhere that gives me a clear idea of what I should be looking for in them. Furthermore after looking on newegg at the pci-e cards they had graphic card specs and it confused me, a little help understanding pci-e would be very helpful.
