It's worth noting that if one compares 768 MB core systems the relative
position of the Tbird/DDR system significantly as its speed doesn't
change (except for codes big enough to fill memory, of course) the 1.33
GHz Athlon with DDR moves up to 560-600, and the price of DDR seems to
be rapidly falling if not quite in free fall.  The killer is those 512
MB DDR DIMMS and the lack of Athlon/DDR motherboards with more than 3
slots...

This isn't to complain about your ranking -- I think it is very useful
and one does have to create some sort of standard in order to compare
price performance.  It is just to note that if one's application DOESN'T
use a GB of core the price/performance rankings can signficantly change
because of the nonlinearities in the cost space.
