i fond a agp 2x 4x voodoo 2000 on ebay here is a pic of it (http://www.falconfly-central.de/identify/Voodoo3_2000_AGP.jpg)
must have been modified did no know that it could do that on a voodoo 3
Nope.
If you look at the picture with care, you can see AGP connector is partially hidden by a card holder's plastic part.
did not see that, but it would be cool if there was a agp 4x voodoo3 card
Yeah, cool optical illusion indeed:)
