Meant to do this a few years ago, then forgot I even had the card until I was going though parts boxes today, so here you go:

Pentium III 1ghz on 440 BX2 100 FSB motherboard
256mb pc100 ram
80GB Seagate Baracuda ata100
Creative AWE64
EVGA 500 watt psu
Antec Titan ATX case

Driver used was 77.72. 81.98 had worse performance.

Serious Sam First Encounter Karnak Demo in OpenGL 32-Bit @ 800x600 Quality settings

Frames: 3372 - Time: 75441ms - Avg: 44.697 - Min: 26 - Max: 70

So, how does this stack against normal Windows 98 titans like the GF3 Ti 4200 128mb and GF3 Ti200 64mb?
Same Serious Sam Karnak test and 3D Mark test run on the other two cards in the same system, but with driver 45.23:
