CPU speeds aren't like the speed of your car. A 300 Mhz CPU isn't twice as
fast as a 150 Mhz CPU. If you check Intel's techspecs, they make a point of
explaining this. Computer magazines have unfortunately contributed quite a
bit to misinformation and misperceptions.

Yep. Javilk's right. The hard disk is measured in milliseconds (ms =
thousands of a second), while the RAM works in nanoseconds (ns = millionth
of a second.) It's much better to do everything in RAM. Put as much RAM into
your machine as possible.

Ah, but Win98 does this too. Better file allocation and automatic
optimization scheduling (defragmentation, disk scanning, removing broken
files, etc.)
I was talking with Microsoft techsupport yesterday and I asked if there was
an upper limit to RAM space. Someone had told me that Microsoft products
(esp. Word) would not use more than 64 MB of RAM. According to the
techsupport guy, there's no upper limit. Go ahead and upgrade to 256 MB or
higher. Windows takes advantage of the extra RAM.
The only limit in Word is that a document can't be larger than 32 MB.
If one uses graphics, then they should be linked to the document, not
embedded. But this is not a realistic limit. To test this, I created a 3,000
page doc and it was only 4 MB. A 32 MB document would be well over twenty
thousand pages.
