Why It Mattered

3dfx Voodoo Graphics helped define consumer 3D acceleration as a dedicated PCI add-in card for Glide-era PC games. It is important in the wiki because it marks the point where separate 3D accelerators became a mainstream enthusiast upgrade.

Collector Notes

For archival use, record board vendor, PCB revision, bus type, memory chips, BIOS label, pass-through cable or TV tuner accessories, display outputs, and photos of both sides of the card.

Used-Market Caution

Before buying used, confirm the exact card variant, PCI or AGP compatibility, pass-through cable needs for dedicated 3D accelerators, capacitor condition, output condition, and tested operation in a period-correct system.

Known Issues

Imported from a derived specification index. Verify exact board behavior, driver support, pass-through cables, and Glide or MiniGL compatibility against primary manuals and period reviews before relying on this entry for buying or repair decisions.
