Connect a real switch into GNS3

in CCNP
I have read a few guides on this but to be honest I'm not too sure what would be the best way to do it given my setup. I have read about buying expensive quad nics, raspberry pi, using a console server.
I have one 2950 switch (cisco) which I want to connect into GNS3 and then connect up virtual routers to it. Eventually I intend to get a couple more switches such as 3950s
My PC is running windows 7 pro and I have one NIC which is on the motherboard
What are the best options do i have and how would I do it to connect my real switch(s) into GNS3?
Thank you.
