I do own a Dual PPro with 220 MB RAM (don't beat me!) overclocked to 233 MHz
(stable, for 2 Years now) and as far as I'm concerned: for a normal
"standard" user, I guess the K6-2 will be the faster/better choice. - Because in
most cases people still tend to work sequential, not in parallel. Though
you could do some things in parallel under an operating system like Linux,
most things that will run in parallel with your own applications on an SMP
box will be the systems own daemons. In most cases they don't have a high
impact on the overall system performance. - Mind it, we are talking about
a "Joe User", not a server! - So if you tend to write a letter, print it,
write another letter, print it. Do some spreadsheet calculations, print the
results. Play a game, write a program, debug it. - You will have more
power available with the K6-2, because you do everything sequentially.
If you start doing the above mentioned stuff more like this:
Write all letters, one after the other, then start printing them with Ghostscript
all together, start spreadsheet calculations and start compiling your sources,
while playing a game while waiting for the printouts and the spreadsheet to come
to an end, you will be better off with an SMP-machine.
And in the latter case, you are a very busy person then and have a great
concept how to save time in your work.
Best regards,
Herbert
