Doing this will have not affect keeping the myth traffic
off the rest of the network because your switch is already
doing that. The Cisco switch is not a hub. It is making
sure that traffic between the front and back end are
only seen on those two respective ports.

The only advantages that adding a second NIC would provide
are:

 - double the bandwidth of the server, although I doubt
that's a problem, even with 100mpbs
 - be able to put an HD homerun on a separate network
perhaps to be able to put it on its own DHCP server
because, for example, your DSL router won't give it a
static address or something
 - ... ?

To second something someone else said, I just bought a
5 port gigabit switch from Best Buy for something like
$40. One of the ports even auto-senses if its connected
to another switch. I'm probably saying more than I should
but I trust simple switches more than managed switches.
