Always interesting to think how Nvidia struggled for its first 2 generations of graphic chips nv1 and nv2 (partnered with SEGA) but made a first big dent in the market with nv3.
It's true that Nvidia is the SGI of the era.
I started university around that time stopped following gaming/computer hardware scene but really felt to me like Nvidia came from absolutely nowhere.
nvidia felt like an odd company, it was small and unknown, unlike Ati or Matrox. But their chip were cheap and competitive with champion 3dfx.
Still impressive how they stretched markets from toys to the highest sophistication.
