Thanks for the info guys. All of my (4) wired computers have gigabit, but I may have to upgrade the wiring. I think it requires at least Cat 5e, and 2 of the computers are only wired with Cat 5.
Don't even bother with Cat 5e. Just do Cat6 if you're trying to put together a gigabit network. As always, check Monoprice.com for the best prices.
The best wireless networks are pretty good, but it's not going to be as fast or as reliable as a wired network, especially if you're moving large amounts of data around your home. If it's not too much trouble, I'd redo the network cables and keep the backbone of your home LAN wired.
But that doesn't mean you should look at setting up a WiFi network too. WiFi is a godsend when it comes to portable equipment or for stuff that doesn't need to push multi-gigs of data quickly.
