	interesting that a 2-core is about what my ibm thinkpad
	3.08ghz is rated at.  it's from '05, used, natch, and i had
	ram and a harddrive upgrade.  just my 0.02cents' worth.

	i leave most of my boxen running 24/7, so it adds up.  when
	my new 2005 custom-built 2.8ghz box died last fall, i hauled
	it out.  i did have to buy the new Dell Core Duo (or
	whatever); that was months of head banging and begging
	favors.  and because my kvm wires are not plugged in
	correctly, i can't get to the server to (1) add X11 + KDE and
	(2) do anything graphic with ~kline on that system.  

	so waiting for somebody i can ask to come over and figure out
	what's going on.  THEN, i'll add my backup 2- or 4-core box
	as a server backup and to run pc-bsd on.

	:-) more decoding than ecoding since i watch a lot of public
	tv streams.  because the house is only around 15meter above
	sea level, i'm keep an eye out for how how the sound rises
	here in seattle.  i'm thinking of planting some palm trees
	and retiring to Nome eventually... .  (do you hear these
	idjots who still believe the earth if flat and that global
	warming is a commie plot || whatever?  ...i just snap off the
	radio!)

	thanks for the core i3 series advice, dave. i'll surf around.

	gary
