I still have my Voodoo 5 5500, remember spending 220 pounds on it
Still one of the best cards ive ever owned though, some of the 3rd party driver out for it now are excellent, I've run Half-Life 2 at an acceptable FPS on it!!!
As far as I know no Voodoo 6 cards which of course was a Quad SMP card *drools* made it to market.
Incidentally my new Radeon EAX1800XT cost 300 quid
