This may provide some interesting reading about the older "key" cards http://www.pcworld.com/article/2034487/the-10-most-important-graphics-cards-in-pc-history.html
I actually owned several of those, especially the early ones. Never had an 8800 but did have a 9800. Had a Voodoo card, Diamond Viper, quite a few of them now that I think of it. http://www.techspot.com/article/650-history-of-the-gpu/
I think one that they should have listed there was the ATI 9800 Pro, that was one hell of a card for the times.
