Why I’m looking at a used video card for my next PC

For gamers, a new video card has long been the king of upgrades. It began with the release of id Software’s Quake, way back in 1996 — while you could play it without a dedicated GPU, the shooter looked so much better and ran so much smoother if you had one. The gold standard was a 3dfx Voodoo card, which was powerful enough for colored lighting effects (gasp).
