About S3 cards and their performance from my personal experience
with XS3:

Not all s3 based cards run at the same graphic engine speed.

So far S3 VESA Local bus cards are not showing higher performance than
their ISA cards. It is almost as if the VESA Local bus interface was
not properly design. I will find out more about this in the near
future by testing an S3 card with a faster local bus interface
(I can't named the manufacturers till I am certain that they 
perform faster)

There appears to be a hardware bug in the 805 chipset (Vesa Local Bus)
which prevents the card from generating maximum performance with XS3.
I have measured other components of the server which are not
affected by this hardware bug.

The fastest benchmarks that I have seen are on a 486/50Mhz ISA systems.

The  486DX2 66 systems have managed to generate up to 20% less performance.

The lowest priced S3 911 (Eclipse) which I have seen is $120 :-)

If you do decide to buy an S3 based card make sure that you get
the fastest memory possible for maximum performance within a 
given class of S3 chipsets.

When I get my hands on a working S3 928 card which works with XS3,
I will let everybody know :-)
