"CAT 5E" is a Ethernet cable specification, that is completely irrelevant to purchasing Ethernet cards. CAT 5E cables can be used with 10/100/1000 Ethernet. CAT 6 is recommended if you are running more than one cable together for any distances at all. I'm not absolutely positive but I think CAT 6 has better shielding, to prevent cross talk at higher frequencies.
As to the question you were really meaning to ask, I'm not sure I follow. Some motherboards have options for WIFI, most don't. WIFI cards to the best of my knowledge never have Ethernet ports. However nearly all motherboards have Ethernet ports for wired networking. And all motherboard over the last few years have had 10/100/1000 connectivity, which would require at least CAT 5E cabling for the best communication possible.
Thanks for the information, I was looking to have more Wired based internet as my home does have alot of steel in it and as such treats the WIFI signal with a Faraday Cage effect grounding it but I wanted to keep my options open for the future when I move out.
