I had something similar!
300Mhz PII - it came in a black cartridge thing.
NVidia RIVA TNT which used the AGP bus on the Intel LX440 mobo.
A whopping 128Mb of RAM and 8Gb HDD.
I recall using a program called WinSplit to split the Nvidia driver over several floppy discs on my bosses Win3.1 machine in the office. I didn't have internet at home and really wanted to play Jedi Knight and Battlezone.
