With what I do, (no 3d modeling type stuff), I don't think anything has changed.
I did have some of the highest benchmark scores for 3dmark 2000 and 2001 using comparable systems, so maybe it did help?
Also flashed the Bios with Elsa's Gloria III, so it does boot as a Quadro2 Pro.
Did the same exact thing to a Visiontek GF2 GTS, including the Gloria III flash.
Followed the instructions at the site you list. Took less than 15 minutes to do.
