What steps other than a heatsink do I need to take to get my voodoo up to the 3000s performance?

Hi Winman486,

you're welcome here.

First of all, any 3dfx hardware deserves always maximum respect, and the overclock is a way to improve performance but it's very risky for hardware. However, you can see if your card is supported  by Voodoo3 tweakers downloadble from this 3dfxzone page: https://www.3dfxzone.it/dir/3dfx/voodoo3/tweakers/

Bye bye
