Which would work better?

I'm looking to improve performance as much as possible. Recently we upgraded the server from an anthlon II processor to an i7 950 with 8GB ram and updated PHP. There is a choice for the jQuery source; local, Google Ajax API CDN, Microsoft CDN, JQuery CDN. Which would probably work better in this scenario? I've got blazing fast internet so noticing the difference is a little difficult for me, however in regards to technical aspects, I'm sure someone can answer.

I personally go with Google Ajax. Once their computer has seen it on any site it is going to be cached and loaded faster on your site. More users will probably see the Google version in my opinion but either way they'll all load about the same.
