AMD T-Bird 1.4 Ghz are selling for $299 here in Canada.
Back in 1997 I paid $250 for my AMD K6-2/350. If I had
gone to 400 Mhz, it would have been nearly $100 extra.
Yes, I have to admit that purchasing the highest end
hardware, only to end up having it be next to worthless
in under three years is somewhat frustrating but the
big deal with computers will be, the more you pay, the
more preformance you get... but the slower it'll go
obselete.
My workplace used Pentium 133 systems right up until
just last year. We purchased a couple of Celeron 333's
because Office 97 wouldn't run properly on the P133's.
Eventually, my company phased out all of the P133's
and replaced them with Pentium 3/733's. In about
another three years these machines will be obselete
too, but they won't be replaced until things stop
(Or won't) run on them, like the newest version of
Microsoft Bloat.
Consider for a moment that Windows XP makes any
machine take a 25 percent preformance hit. Then
consider how Windows 95 made a preformance hit on
486 machines that were previously running Windows
3.1. I gather it was just as much of a preformance
hit, if not moreso.
I could have stayed with my K6-2/350 but I found
increasingly that more and more apps that I used
demanded more and more power. So, I recommend to
you only to upgrade if you find that your apps
just don't run well anymore and you haven't
reinstalled your OS.
