Separate high speed network

I have a home network and FiOS high speed internet, which is fine, all units have 10/100 NICs. I just got three Gigabit NICs which I would like to install in three computers and create a GB network just between these three for high speed file transfer. How would I go about this? The other network should not see or have access to this new network.
Thanks in advance!

if you need to connect the 3 nics to the other lan, get a router instead (again with gigabit internal) and link the wan port to the other network and the 3 new nics on the internal lan.

Thanks for the quick reply!

Rats! Should have mentioned I will connect the three with a Gigabit switch. I was more wondering about how to make the traffic between the three machines go over the fast GB network, but their usual traffic over the original network. DO I need to set the three GB NICs to a different fixed IP subnet?

I see you want to run dual nic on all these machines.

Lets assume you leave the main nic on the router and it gets the default gateway and dns from this router.

What you now do is hook all the new nic to the gig switch as you said. You then assign a ip address to each machine from a new subnet. As long as it is outside the scope of you main network it doesn't matter. The secret to making this work is leave the default gateway and DNS blank.

So now it pretty much just works. Traffic between the machines will use the old nic if you use the old address. It will use the new nic if you use the new address. Anything else will go to the router since it is the only default gateway you have.

Thanks to all who answered! A final question:
I gather that if the slow network is 192.168.15.xxx, then setting the three new NICs to 192.168.25.xxx as the high speed network, hook the new NICs together with a GB switch, the routing will take care of itself? Or would 10.0.1.xxx be better? Subnet masks? The 3 GB Nics are fixed IPs, no DNS or gateway, and the only 3 NICs on that switch.
I tried reading up on subnets and masking but my hair began to hurt...

As long as they are in different subnets it does not matter what ip blocks you use. If you were using real IP blocks where you don't want to waste ip you would use a subnet mask of 255.255.255.248 but since you are using private ones it tends to be easier to use 255.255.255.0 for the mask.
