[geeks] anyone know about this? 72-core, 48GB computer?

Blasted iPhone auto-correct!!!

Yes, that's what I meant...

There is a dual core Atom, the 330.

I'm about to build my home test network with a D945GCLF2 MB running  
WinServer 2008 R2 which is x64 capable acting as Primary Domain  
Controller, should be fine with just 2 Gigs of RAM...

I want to see an Atom MB that supports 4 Gigs of RAM ;^)
