" When Intel introduced the Prescott based P4s, it was a fairly significant
" change to the P4 architecture (much longer pipeline, several other changes).
" To distinguish it the older "Northwood" cores which Intel was still selling at
" the same time, they added an "E" to the product name of the Prescott cores.

aha!  so 'e' basically just means 'prescott' - just the 90nm process, 
or 130nm also?  what about p4 extreme editions?

" At the same clock speed, Northwood is faster than Prescott, but Prescott was
" eventually released in higher frequencies, and in dual-core configurations
" while Northwood was always single-core and retired sooner.

hmmm...  since i'm looking at socket 478, dual core is [i think]
irrelevant.

i'm noodling performance upgrades for my gf's machine, which currently
has a non-hyperthreaded 2.8/533; i don't know if the chipset supports
hyperthreading, or if that'd get her anything under xp pro.  ebay has
3.2/800 cpus for ~$30...  the ram is already pc3200.
