The 3Dfx Voodoo 2 and the Nvidia Riva TNT were the pinnacles of the early era of 3D graphics. Both were released in 1998, and while I owned the latter, the Voodoo 2 was the faster of the two, despite the inconvenience of requiring an existing 2D graphics card. The Voodoo 2 is naturally memorable, and it's a regular presence in retro PC builds. As the YouTube channel Bits und Bolts (Bits) found out, the cards' capacitors can and will fail in time due to the rarely discussed pyroelectric effect.
In a lengthy video, Bits diagnoses why one of his Voodoo 2 cards is intermittently failing with graphical corruption, with no apparent pattern other than the issues appearing after a short time of use. After much digging, he figures out that the problem seems related to the card's power-delivery circuitry by inspecting how resistance changed at the component that converts 5 V to 3.3 V.
Plus the cost of a regular graphics card. You also had to buy a sound card in addition to all the components you still need today. And I was 15 years old, so coughing up another ~$700 for two of the beefier cards would mean a whole lot more working during summer break.
