Good info, Robert. Thanks.
As promised, and in case anyone wants to try it, the instructions for the new nVidia driver are here:
I had no trouble with this, but I've done this kind of thing before. If you are not sure of what you are doing, I recommend not trying this unless you are looking to learn some things. When it goes well, it's wonderful. When it doesn't, it can take a while to clean up the mess. The instructions are clear, but a bit complicated.
