I had a bunch of the early "3D" cards, like the Rage II, but the most influential to me was the Geforce 2 GTS, mine had 32MB of DDR SGRAM and it was astoundingly fast compared to anything I had used before. I could play Quake III and UT in full 32-bit color at my monitors maximum 1024x768 resolution! What a beast! I find it kind of funny how picky we are about graphics these days when back then I was worried about my frame rate tanking if I didn't use 16-bit color.
