I think, its the only Card from 3dfx that support this feature but some people say it doesnt support it.
Is that right ???

According to my PowerColor EvilKing Voodoo4 Box and Manual, the Voodoo4 should indeed support 4x AGP.

However :

http://www.muriwai.co.nz/new_zealand_computer_services/video.html

There, the PowerColor Voodoo4 is listed as 2x AGP only (?)

http://www.3dgrafikkarten.de/karten.php3?Name=Voodoo4%204500%20AGP

Here, it is listed as 4x AGP (???)

So you see, there are conflicting Information about the Voodoo4 ::)
That's probably the reason for the confusion...

I've searched the official 3dfx Voodoo4 4500 AGP pdf document, but there is no statement concerning 2x or 4x AGP :P

Thanks for the material + Information guys.

Hey Falconfly you have a great homepage.
