Extra RAM won't make a difference unless you're using significantly more
virtual than real.

You might also check out the benchmarks at
http://www.informatik.uni-frankfurt.de/~stst/mathstef2.html. They're
consistent with what you're saying. G3's and the faster 600-series PPC
processors (and even a Linux Pentium) trounced a SPARC Ultra 1.

SUN's have never had particularly good speed/cost relative to the
competition. To me, the big advantage of SUN has been that it has
offered a stable foundation for premium software. Things like CAD
packages may run faster on PC's, but the SUN implementations almost
always have fewer bugs. This doesn't seem to be an issue with
Mathematica: at least on MacOS, I find it works very well indeed.
