is it possible to setup someway to have two video cards work together? help! never tried this

i got a voodoo3 3000 pci a couple years ago, and got a voodoo3 3000Agp a few months after that, my friend borrowed my PCI voodoo for about a year and a half and i am still using the AGP one, and i am just wondering, since i don't feel like buying a video card, if it is possible to use both at once and set them up somehow to make them work together, if anyone has a link to how to do this or good instructions on how to do it (if its possible to do this, i think i remember hearing about people using 2 video cards at once a while back) please post a reply, or send an e-mail to bigearL6961@home.com <br>

ps: maybe i just have to pop in my other voodoo, i have no idea, don't want to attempt this if its not possible to use both<br><br><i>This message was edited by matt6961 on 24 Jul 2001 12:04 PM</i>
