If you plan to use them on the same network to increase the link speed you should
consider using adapter bonding. That means that both ports are tied together to a
virtual "bond0" interface wich has the speed of both adapters combined. But your
switch has to support that (this is usually called port trunking, usually only the
more expensive 16-port and above switches support it, just have a look at the manual).

Just assigning two IPs in the same network won't improve your network performance much.

To use bonding on linux take a look at this kernel patch:
