Short answer:

No.


Longer answer:

Given the right application or benchmark you could certainly "measure" 
a difference; however, you almost certainly would not be able to 
"notice" the difference while you are using the machine.

Tests done when PC100 and PC133 were leading edge or mainstream show 
that if an application is memory sensitive there is a few percent 
difference in performance between CAS level 2 and 3 memory sticks. 
While the difference between PC100 and PC133 is certainly larger than 
the difference between CAS levels you are still unlikely to "notice" 
the difference.

So if you're using the machine for work for compute intensive tasks 
faster memory will probably pay for itself in the long run, especially 
given how cheap memory is these days. (Selling the old memory makes the 
pay off even more likely). For home use I wouldn't bother unless the 
money involved is inconsequential to you.

Note that having enough memory vastly dwarfs the question of how fast 
your memory is. Given how inexpensive memory is these days I'd say that 
everyone should have at least 512 KB of RAM.
