I am getting a new pc. what is the best way for me to transfer my files from my old pc to my new pc? I have soemthing about getting a crossover cable? As long as both of my pcs have a network card. Well my new pc will have Lan on the mother board but I am not sure if my old pc has a network card. When I got comcast cable moden installed I think the technician installed an ethernet card. Is this the network card i need? Any help would be great thanks!
