I have tried my voodoo5 on a slow CPU and it didnt run too well (with or without FSAA),and I doubt he wants to search ebay for a card that is quite rare and expensive (usually around 70$),especially when he can have a v2 or v3 almost for free.not mentioning the size of the card,if he has a small case,he will have a hard time fitting the card in there,and old pcs usually have small cases (at least around here).anyway,its his choice
and voodoo47=ps47 if you havent guessed.voodoofiles&3dfxzone,and couple of other places as well.3dfx is still my game
