My first video card was a 2d card made by Matrox. And first 3d was a voodoo card, which sucked because the early forms of those cards required a 2d card to be run with it, and it caused constant problems. But when you could get it working it was mind blowing, i remember running need for speed 2 with it, and the graphics in 3d mode were so amazing compared to running it in 2d. Lots of incompatible 3d games though.
My first 2d/3d combined card was the Creative 3dfx banshee card (basically voodoo chipset i think), think i got it around 1998, a great card considering it was one of the first cards to do this.... except it overheated and locked up a lot so i got a cheap little fan for its heatsink and it fixed the lock ups.
I think nvidia is the company that actually bought out voodoo so in some way they live on.
Had all of those too, myself. (We ARE old...)
The first 3D PC game that hit me was Unreal. First level. Everybody who was there at the time remembers it. Looked amazing, back then (Glide API!!).
A second game which did a job on me back then - graphically - was Quake 2. Switching from software rendering (which we all knew too well back then) to OpenGL and BOOM! Starring at that 1024x768 CRT 50Hz VGA monitor every day for weeks. Radiation should have made me blind by now?
