Memory timing

Hi!

Can someone please point me to some easy to understand info on memory
timing, how it affects thinsg and how important it is?
For example now I'm looking at two Kingston HyperX mem-sticks, they are
timed:

PC3200 CAS Latency 2 (2-2-2-6-1T) ($125)
PC3200 CAS Latency 2 (2-3-2-6-1T) ($100)

There's a $25 difference between these two sticks, will that single digit
difference in memory timing make any detectable difference whatsoever at
stock speed or slightly above?
Alsom from the faster of these two there's just a $2 difference to this one:

PC3500 CAS Latency 2 (2-3-3-7-1T) ($127)

For starters I'm gonna go with 400MHz FSB for the Barton XP2500+ I'm
getting, but as I'm getting a water cooling rig I might be tempted to take
it further, but how far would I need to go to make up for the worse timing
of the higher speed ram?
I realy want to try and understand these issues as they are of importance in
overclocking so any help would be apreciated!

Best Wishes
Thomas

There's a real nice primer on memory on the Corsair website. It will answer
most of your questions in great detail.
