What kind of performance loss can I expect when using Wildcard Mapping for ASP.NET MVC in IIS6 for images/videos?

Question

I'm currently looking at server prices and IIS6 is looking cheaper then IIS7. I want to try out some ASP.NET MVC w/ extensionless URL's and from what I see, I can use an ISAPI or a Wild Card Mapping option. I'm planning to stream quite a lot of media and I'm curious how the Wild Card Mapping option would affect my performance.

Has anyone done any performance tests or have a pretty good sense of what might happen if I do this?
