Gigabit on existing 10/100 Cabling?

[Styg]

I want to get gigabit speeds on my existing 10/100 UTP cabling. I read that I just need to buy a gigabit switch to replace my 10/100 and I'm good to go since all my computers' motherboard have onboard gigabit lan. How true is this?

I'm getting 100mbps (LAN) speeds on my current setup but I really need to up it to gigabit speeds.

You can use cat5 cable for a gigabit network, but cat 5e is preferred if you are starting from scratch. So yes, it sounds like all you need is a new switch since all the machines are already gigabit ready.
