well, technically speaking, I believe windows only allows for one internet connection -- or more specifically, one gateway. All of your traffic gets routed through one gateway (unless you have virtual machines running or something that emulates two separate computers)...

so two ethernet ports might be helpful for improving throughput on one network, but typically one operation goes through one port at a time.

So more ports is a bit of a waste unless your computer is routing traffic like a proxy or firewall where it could route traffic from one port to the other...
