Good advice, although personally I use Visual packs 1.11, 1.2 and XT instead of vibrant morrowind, and don't use MCA. If you're going for a complete graphical overhaul you should also look at some of these.
Change the line DontThreadLoad=0 in morrowind.ini to 1. That'll stop it streaming anything, but it makes loading times longer.
...or prevents the game from jerking around from streaming stuff in, even on a high-end PC?
