Shredder is scaling 3.3 at quad single core, so that'll be like scaling of 4 at
dual core quad or so?

junior was single core and fritz will not be scaling well either (deepfritz8).

We know all this already from 8 cpu Xeon machines in fact. See results donninger
posted once.

If you don't run well at 8 cpu xeon then forget dual core.
