To answer the OPs question about "why," it's because those three programs, when they create a "virtual machine" to run Windows, they also create a "virtual graphics adapter" -- and you don't get access to your graphics hardware directly. In Bootcamp, you do. That's why for demanding games and certain other video-intensive programs, Boot Camp installations work better.

For most applications (surfing, office productivity, etc.) the virtual machines are essentially indistinguishable from Boot Camp.

One note: VirtualBox is free, whereas Fusion and Parallels are not (although they each have 30 day free trials). You will need to buy Windows, however, as chscag indicates, the system builder OEM versions are usually the cheapest.
