Does Adobe Flash still run on the Mac Pro?

I am interested in purchasing a Mac Pro desktop computer to use for music production. I have one concern though, which is how the internet cooperates with this machine. I have read that Adobe Flash will not run for Power Mac G5's. I'm wondering if the same situation is true for the August 2006 version of the Mac Pro (or any versions of the Mac Pro for that matter, though this version is the one I am most interested in). Any help and information is greatly appreciated. If anyone has any feedback on the August 2006 Mac Pro, that'd also be awesome. Thanks.
