Good enough
CPUs these days (1.3 GHz+) are faster than
anyone really needs for normal use. Things
like word processing, email, surfing the
Net, money management, etc. A faster CPU
won't do much for normal users. (Oh, it will
give you bragging rights.) More speed will
start programs faster -- anywhere from fractions
to a few seconds quicker. It won't make a
noticeable difference in how fast most programs
run. Spend your money on more and faster
memory -- 512 MBytes of 400 MHz DDR RAM,
for example.
With Windows XP you should get a 2.0 to 2.8
GHz CPU for everything except graphics intense
use, like 3D games. For Windows 98, even 233 MHz is not all that
slow -- that's what the club's eMachine has.
Manufacturers have turned CPU speeds into
a horsepower race, because it's a simple number that was important
when CPU speeds were 33 or 66 MHz, and it's
been touted ever since. The funny thing is,
bargain computers come with only 128 MB or
256 MB of memory. Not that there's anything
wrong with that, but 512 MB of memory would
improve performance much more than a faster
processor. [more]
Of course speed does matter to people who
do a lot of graphics, play the latest 3D
games, or edit video. If that describes you,
build a system with dual 3.2 GHz CPUs, 1
GB of 800 MHz DDR memory, dual 15,000 rpm
disk drives, the latest 3-D accelerator,
and have at it. The rest of us will be perfectly
happy with a system that's good enough. It
will also run cooler and quiter, and be more
reliable.
A couple of pretty good computers
Desktop:
- CPU: 2.0 GHz Celeron or Athlon XP
- Memory: 512 MB of DDR SDRAM
- Storage: 30 GB hard drive
This CPU/Memory combination should be good
enough for quite a few years before it becomes
outmoded. By then, that really *razoo* machine
will cost a lot less and it may be time to
move on. CPU speed isn't the only thing that
gets outmoded either. You'll probably want
a new machine some day for some other reason
than just more CPU speed.

Notebook:
"Good enough" Notebook
PC's won't
have the same capability as good
enough Desktops.
They're still good enough:
- CPU: 1.13 GHz PIII-M
- Memory: 256 MB RAM
- Storage: 30 GB hard drive,
One more note: Be sure the computer supports
USB 2.0 for peripherals. That could be much
more important to you than a little extra
computing speed.
A performance computer
If you really want more performance, for
whatever reason -- hedge against future needs
-- really crisp performance -- you just *deserve*
it -- whatever -- then go with a computer
as powerful as the one below (unless you're
a "gamer", or somebody who needs
maximum performance):
- CPU: 2.8 GHz Pentium 4
- Memory: 1024 MB DDR at 400 MHz. The key word
here is DDR (Double Data Rate).
- Disk Drive: 80 GB, 7200 RPM
