This site has a video on the King James Verses NIV & NASB and no doubt there are differences which are made also because the King James is non copyrighted and to make a copyrighted versions it has to be different in some form so it would not be a copy of the King James. But it is also easy to make a more better translation from the original languages used as the King James picked out the word they wanted to use in translation. The King James is better then these others in my opinion and many others feel that way too. Here's a video on it.
This is the the remnant of God site.
