IMHO, I'd go with the Tyan Tiger 100 (bx chipset) and set the fsb to 133. I ran my 650's @ 866 for over a year and never had a problem. Due to the higher AGP speed, I ended up with a Matrox G400 which never once gave me a problem. The memory was standard Crucial 7.5T 222 PC 133 which is now dirt cheap. Just a thought.
