Split things up when they get slow. There is no good guide to when they will
get slow because each system is different and has different load patterns.

Machines with Intel CPUs will beat almost anything for integer math, will
perform OK for floating point math (which is fine as you hardly ever need it
for an ISP), and will perform quite well for network and disk IO.
If you do some benchmarks expect the latest Intel/AMD-based machines to
outperform your Sun and your Mac on every test.
IO is one area that PCs can really stand out. Software RAID on Linux with
ATA-100 hard drives can easily outperform Sun hardware RAID arrays costing
100 times more money.
Another issue is that of reliability. If something dies and you go off-line
then you lose money!
Use RAID for all hard drives. Wherever possible have several almost
identical machines so that you can swap parts when things go wrong. Having a
Sun and an Apple is a bad idea IMHO. If one of them breaks you can't easily
get replacement parts. With PCs you can have three identical PCs so if the
most important machine dies you can swap parts with less important machines.
