Now, I may be preaching to the choir in your case, so let me answer your specific question. Will there be an increase in network traffic with SSL enabled? Yes. Will that saturate your bandwidth? That is hard to answer without knowing what your current bandwidth is.
What I can tell you, based on Microsoft's own performance testing, is that you will need 200% more processor power to handle the public key encryption (PKI) overhead. So, you will want to watch processor utilization carefully if you do enable SSL on your existing Exchange server. Again, enabling SSL is not an option in my opinion if you want to allow Internet users to connect.
