On the GFX card side of things its ,just 3DFX that got so expensive, Some sound cards keep there value aswell, Roland, Yamaha, some of the sound blasters... The only reason Voodoo is so expensive is the fact that its the only line of cards that fully support glide, and in retro PC turms nothing beats it, and glide wrappers dont even come close, its the main reason I am out hunting for one... Same could probably be said for the sound cards,the Roland and Yamaha had a very unique sound, chiptune musicians like them especially,but in all fairness I grew up with a SB16 so I'll just stick with it becouse I am use to its Midi Sound.
