Perhaps I missed it further back in this long thread, but I think that at least these latest posts are missing the fact that Gandalf himself is enhanced when he returns--the White Wizard instead of the Grey Pilgrim. There are numerous instances where Gandalf's enhanced power is mentioned, ranging from the quote above about Aragorn, Legolas and Gimli not having weapons to hurt him, to the destaffing of Saruman, etc.

So Sauron may have enhanced the Witch King's power, but Gandalf's power seems to have been enhanced on his return by Eru...

All of which goes to show to me that Peter Jackson completely misread the whole thing and changed the story for some desired dramatic effect...
