Do you have two separate 100mbit internet connections? If not, your not benefiting at all. You'll hit the peak of your internet before you ever hit the peak of ONE NIC, unless you have a 10mb NIC on a 15mb cable/fios connection? As stated above, having dual NIC's in a soho environment is pretty much useless unless one of them goes bad. If one does go bad, I'd be wondering why it went bad in first place. I only use dual nic's in my server's here at work for load balancing purposes (large cad & adobe files)
