Also remember that Zorro network cards are all 10Mbit network speed. PCI bus will let you use a 100Mbit network card.
If it was me, I'd buy a PCI bus, Voodoo3 and 100Mbit network card, and keep the CVPPC for a while, just to make sure you're happy with everything. If you're satisfied with the Voodoo3 then sell the CVPPC, if not, keep the CVPPC and sell the Voodoo3. You can use a Prometheus and Mediator PCI bus with network card at the same time as CVPPC if you'd end up preferring that to Voodoo3, but I think the Voodoo3 features will still beat CVPPC even with the difference in bus speed.
