MadOnion 3DMark2001SE scores as follows:
1) 40.71 dets: 7929 3D Marks
2) 40.72 dets: 7954 3D Marks
I have a 200+ jump in 3D Mark score since going to the 40 series dets. I like it
Plus all my games (Q3, MOHAA, RTCW, BF1942 demo, UT2003 demo) play great.
If you have a GF3 or 4 and run Win98, I cannot say anything other than give these drivers a try
