Is it possible to increase bandwidth by using two nics. I know that if you are running advanced server. That you can configure load balancing is there anyway to increase the bandwidth somehow.

Answer is it depends. If you have NIC's that support link aggregation (sometimes called Ether Channel or Ether Trunks) and a switch that supports this you can increase the bandwidth to the switch.
Link aggregation drivers usually have several modes- load balancing (no increased throughput), fail-over support (no increased throughput) or ether channel (increased throughput).
Some Cisco switches support up to 8 ports (connections) being trunked. Your limiter here is going to be the PCI bus in your machine- at best you will get 650MB/s through it, realistically only 350-500 MB/s (other system devices want bandwidth too!). With multiple peer PCI buses you can get around this, but you are deep into hardware at this point....
