Not that I've heard of, they should be fine with bootcamp.

Looking at the tech specs here: http://www.apple.com/imac/specs.html, they have pretty standard video on all of them, nothing weird that would cause problems.

The ones that have dedicated ATI or NVidia graphics cards will probably be a bit zippier than the baseline model. The lowest price one has integrated Intel graphics, which will work fine but isn't quite as powerful as the dedicated graphics card ones. However you probably won't really notice unless you do some pretty complex stuff. But that wouldn't be a bad upgrade to guarantee that you've got solid graphics.
