Well, my biggest reason was to support 4+GB of memory. When I bought
my new system I purchased 4GB of memory with the idea of adding a
second 4GB of memory so that I could have fast running of mytharchive
as during the processing most of the data will be in cache.

BTW, if anyone thinks I am nuts for wanting this much memory for this
I paid $300US for 4GB of PC3200 REG ECC around a year ago and I assume
the price will be lower now.
