Hey , what is the difference between a single LAN Mobo and a dual LAN mobo? and what are the differences ill see in peroframnce and is it worth it? i don't really know what a LAN has to do with a motherboard... Please help out as im looking at the Asus P6X58D-E and Asus P6X58D-Premium and not sure if Dual LAN is worth the money and that.. Also i'll be using a corei7 with this and Corsair XMS3 (6GB) or maybe the dominator version... another question would be is the dominator worth the extra £30? Can you really notice any difference in speeds?
