I am in the midst of the same conundrum myself. I've managed to distill it down to this: 1) Price. The Redeon LE is 60 odd bucks, the Kyro II from Hercules is a little over 100. (although I keep seeing wonderful things regarding the Vivid!XS 32 meg card that I can't find ANYWHERE!) 2.) OS. It would appear that win2k is still a sore point for Radeon. On the other hand, if you are into Linux, there are currently (that I'm aware of) any drivers for the Kyro II, where the Radeon works like a wet dream. 3.) Game performance. The Kyro is a bit of a wild ride, it has fantastic highs in performance, rivaling Nividia absolute best, to barely being able to hold it's own w/ the MX cards. The Radeon is a bit less dramatic, offering a more average performance across the board, always above average. Look to the reviews of the games you play/plan to play, and go from there. I know this doesn't answer your question, but I hope it helps you decide.
