I'd love to see what a quad socket 64 core Interlagos system would pull in. Not that it'd be efficient, a GPU would be far better, but just to see the numbers.
Interlagos is basicly a set of Istanbul CPUs, so here - calc yourself. ;-)

(For
sha256d those 48 cores do about 150 MH/s or ~3.125 MH/s per core)
