hehe dont get so pissy
all durons 950mhz and lower are based on the spitfire core
all durons 1ghz or faster are based on the morgan core
there isnt any speed of duron where you have the choice of either morgan or spitfire
they all have aluminum interconnects so the speed really cant get that high... thats why 600mhz durons could overclock 1.1ghz and 950mhz durons could only overclock to about 1.1ghz
the morgan core is a little faster then the spitfire at equal clock speed, but its really not much faster (although the morgan does have sse so if you use apps that can take advantage of sse you will get a good boost with the morgan)
just remember that some of the older motherboards that dont support the new athlonXP's also dont support the morgan... for example my server is an asus a7v, it used to run a 650mhz duron... when i went to upgrade i got a 1ghz duron, but it wouldnt work, not even with the newest bios... the duron worked fine in other boards though... i ended up upgrading my server to a 1.3ghz athlon
