Picked a Sepron 3100 * ECS NF3a combo up at Fry's Retail Store for 89.99, and 1 gig kit of Corsair Value ram cas 2.5 for $49 after rebate, and a beutiful demo cast for half price at $39.99, and a Radeon 7000 for $19 after rebate (for my Mom's web/mail rig).
The chip is a Palermo Core (64 bit) oc'd no problem to 250 fsb for 2250, 1t, stock volts, ram at 166 divider (running at 204, 2.5,3,3,8) HTT is at 3x.
This is for my wife's computer. I already had 2 60 gig HDs and a raid card for raid 0, floppy, and DVD drive. I had the original unused heatsink from my X2 (since I use a big typoon on it). I was able to plug that stripped raid set into the mobo, boot into safe mode, remove a few things from device manager, reboot, load drivers and works flawlessly without a Windows Reinstall.
I upgraded my Mom's computer from a P3 800 to my wife's old components (which were mine a long time ago) Barton 2500, NF2 mobo, and 512 meg of ram.
So two computer upgrades, total cost after rebates: $215.
