Found this popping around and was wondering.

Wouldn't the main part be Internet speed? If you have a super slow Internet connection with this fast card wouldn't it be the same as an on board port? I can't see how this would help out in connection times and all that stuff.
I have an onboard Ethernet port and works fine with very smooth speeds. Play games just fine.
I just don't see the need for anyone to have this.
