All games are fillrate limited at higher resolutions. But if you
aren't getting 36fps at lower resolution (640x480) in GPL or 30fps in
N3 then the fillrate isn't the bottleneck on your system.
The processor would then be the bottleneck, so adding another Voodoo
for SLI (which does increase fillrate) or a faster Voodoo won't give
you much improvement.
If the processor is the bottleneck you can either upgrade to a faster
one or off-load some of the tasks, the GeForce card off-loads much of
the graphics work to its own processor. You might also consider
getting an SB Live sound card which uses very little processor and has
a digital gameport.
If you do get max framerates at lower resolutions, but drop off when
you go to higher resolutions, then fillrate is the bottleneck. The new
Voodoo 4 and 5 cards will get you back to a solid 36/30 in that
situation.
