lol.. a good switch, 2 network cards and you\'re set. That\'s what i\'m using anyways. The USB connection is as fast as coax. If anyone was gonna link 2 comps together using coax. They\'re better off just using usb. (saves em a whole pci slot) At the moment CAP5 is the best to use (imo, for gaming that is). Cap5e which is faster, but only good for a short distance. There\'s also Cap6 and fibre optics which gets alittle too expensive.
PS, a router is for networking different networks together (although alot like a switch) A switch and hub are for making these networks. A switch is smarter. Doesn\'t send out info to everycomp, just where it needs to go. All you need is a switch or hub if you\'re gonna go cap 5.
