I believe that you should not put too much importance on the actual
figures if your PC is working as you want it to work because there are
many variables. If it ain't broke - don't fix it!
The Novabench tests might show an area where improvement in one area
could be significant and not too expensive
There has been a very helpful thread running in a Melbpc news group on
computer speed with many contributors
To quote Jason Keast :-
" .............it has been many years since you could use clock
frequency as a simple way to compare performance.
They no longer try to make a single processor run faster and faster -
it gets too hot and, therefore, noisy (because of all the fans).
Instead, they make everything smaller, put more (independent)
processors (ie cores) on the one chip, and improve caching, etc.
By making things smaller not only do the chips use less energy (per
transistor), but the electrons don't have as far to travel - which
means calculations are performed faster (for the same clock speed).
Having several cores means that several tasks can be done
simultaneously - without time-sharing the one CPU. It's also easy to
save power by automatically shutting down cores that aren't needed -
especially useful for laptops.
The latest chips use 32nm technology
(http://en.wikipedia.org/wiki/32_nanometer), have 6 cores, 8M cache,
and pack over a billion transistors onto one chip!
No wonder they work better. :-) "
