I would go with the Gig IO controller.

But you are never going to push 4gbit of traffic through this box ever.

You probably wont break 500mbps.

Or lower, depending on your features.

So you might as well use a one or two gig ports trunked to a switch.

And if that switch is something like a 3550, then you might have some 
interesting options.
