1) Tseng Labs ET4000 - one of the most popular 2d card in early 90's
2) 3dfx Voodoo - the very first 3d accelerator for the masses. Breakthrough in gaming due to alpha blending and antialiasing. No more pixelation, dizziness and headaches playing FPS's, YAY!
3) Riva 128 /ZX - 2d card with build in 3d accelerator, also with AB and AA support.
4) Matrox G200 - Environment Mapped Bump Mapping
5) GeForce 256 - hardware T&L support.
6) Radeon 7000 - ATI joins the game with proper 3d card which finally is not crashing and being incompatibility with 99% of the games LOL. Their previous Rage series was a nightmare. Btw there was a "Fury" card already back there ATI RAGE FURY MAXX, AMD is not being originall this year
5) GeForce 3 - programmable pixel and vertex shaders!
nVidia from FX, ATI from 9XXX series started going crazy throwing out dozens of different models within the same family, so it became more advertising then revolutions.
There should probably be some more options in the middle and after but thats what i remember being a posh hardware back in the days.
@ UP Btw i had 4200ti with some of the shaders unlocked and oc'd at performance of almost 4600, good times
Good call with that SLI, forgot about it.
