PRECISELY MY POINT - dear oh dear, some Athlon chipsets (KT133A, say) don't
get on with W2K.

This friend killed his system trying to install SP2.  He wiped it clean and
went back to SP1.

NT4 is roughly as bad for playing games as W2K.  If you play games you're
considered a masochist if you use NT/W2K.  Simple things like graphics cards
and sound cards are not supported sufficiently well under the big OSs.  Many
games explicitly state that W2K is not supported.

I get this problem even when NS hasn't been started on my system.
Re-starting PS clears the RAM completely.

By the time you've factored in the cost of 2 CPUs and the motherboard to
support them, you've added 40-50% to your costs, and MP doesn't give you a
50% performance boost over the single processor system. It's around 30% as
far as I can tell.  If you absolutely must have the best performance
available now, then yeah, get the dual CPU.

DDR gives a performance boost of 5-10%.  But DDR is worth buying because it
is 5% extra performance for 2-3% extra cost.

LOL.  The P4 is a pile of crap.  In a year's time it'll prolly be worth
considering.  AMD's roadmap seems to show it falling significantly behind
Intel next summer, I reckon.
