Spend $$$ on third party bandwidth monitoring tools. The Windows's tools
only monitor what is at the particular machine itself, not the whole
network.

No, it will not. It just means that anything *it* does will be at 10mbps.
Sometimes you can use those old nics as bandwidth restrictors to keep
certain machines or users bandwidth limited (basically you are "trottling"
them).
You can also use them on the Internet side of a Proxy or Firewall to help
trottle the outbound load hitting the Internet Router. Remember that the
Router can only run at the speed of the WAN link on the Internet side, yet
it is receiving at 100mpbs on the LAN side,...it has to "buffer" all that
extra traffic until it can send it. Reducing that to 10mbps takes a load of
the Router and divides it up with the Firewall/Proxy. The Firewall/Proxy
will buffer between 100mbps and 10 mbps, then the Router buffers between
10mbps and the T1 (1.45mbps), or DSL, or ISDN, or whatever.
Also keep in mind that many Routers, like the Cisco 2500 Series only runs at
10mbps on the Ethernet Interface anyway.
