Hello I have a voodoo 3 2000pci and I want to update the bios I found many bios in www.3dfxzone.it and in www.welcome.to/3dfxbios, in 3dfxzone they not diference between agp or pci, I tried the agp bios and it works ok, and I have two questions:

1º:Don´t care if I put agp bios in a pci card???what is the diference between the two bios??

2º:Can I put a voodoo 3 3000 bios in a voodoo3 2000 card??it will give me some advantages???

My advice is to not flash the card- The performance difference is slight between versions and there is a good chance you will kill the card by flashing from 2000
-> 3000 due to ram or gpu not being able to run the speeds during boot.

Far safer to use overclocking tab and bump up speed a bit at a time.
