palamino is on a .18 micron core, so it runs hotter and won't overclock as well.
tbred A and B are newer, on the .13 micron process, run cooler and overclock better.
if you're into overclocking, people have been doing very well with 1700+, especially considering the $50 price tag.
otherwise, get whatever suits your needs for performance/price
your board will support any athlon xp, regardless of the core
