I'm planning on purchasing TP-Link N900 wifi card that requires a PCIe X1 slot, but my mobo doesn't have one. PCIe 2.0 x16 is the only open slot. I'd like to know if the wifi card works normally in a PCIe 2.0 slot. And does it have any effect on my system because i heard that it might slow down my GPU since 2 PCIe x16 slots are being used but i'm not sure if it's true. Thank you
