3D Spotlight : Hardware : 3dfx Voodoo 3 3000 PCI review

3dfx Voodoo 3 3000 PCI review
Posted by Thomas McGuire on January 31, 2000
Company: 3dfx Interactive     Product: Voodoo 3 3000 PCI

The Voodoo3 3000 PCI is the latest addition to 3dfxs PCI range. Being an owner of a 2000 PCI for some months now I was looking forward to see what I could get out this card.

Being a PCI model its obviously aimed at those out there who have no AGP slot on the motherboard, or those with video cards soldered into the motherboard (much like myself). So after finding the card hidden amongst the almost ridiculously large press kit, is it worth buying? Read on & find out more.

We won't go into much details on the Voodoo3 chip itself in this article, if you want to learn more about it be sure to check out our own review of the AGP version of the Voodoo3 3000 here, you will find a more comprehensive explanation on Voodoo3 chip features, visual quality and details.

In this article we will be focussing exclusively to the overall performance of the PCI version and its position on the market, below see some Voodoo3 general specs.
