great answer...
PCDAD have a similar setup xcept using da
Mobile Barton XP 2500+ K7N2 Delta.
oc'd a bit 
12.5 x 200 fsb, 256*2 using 3200 green Mushkin dual channel @1.625v. That's still below ur desktop barton's default vcore.
ya gotta love those oem laptoppers, unlocked and happy to run above specs.
