You can have a voodoo card as an addon above your other card. If you wanna play N64 emulation I'd recommend picking up a voodoo 2 from ebay.
jollyrancher said:If you already have a gf3+ or Radeon 9600+ I really don't think it's worth it to buy a Voodoo card for N64 emulation. Even if the new Glide64 is amazing, who's to say that Rice's/Jabo's/gl64 or another plugin won't top it in a few months? Regardless, Jabo's plugin worked flawlessly on my old gf3 with 90% of the games and Rice's plugin was great for the few games that had trouble (NFL Blitz, All Star Baseball 2000, etc).
