I'm not sure 6 games means a lot...  IE Crafty played a match vs Phalanx last
week on one of the servers, where I had a big hardware advantage, and I watched
Crafty lose the first 4 games in a row, before it won 24 in a row.
Statistically unexpected, but it happens...

And I don't have to 'imagine' how it does on a 'quad' I get to see it every day,
and it is very dangerous.  There is going to be a Crafty VS GM demo at a Linux
conference somewhere in Europe.  More details when I get 'em.  The folks there
are borrowing a quad xeon and are going to run crafty 'full-blown' with all the
5 piece tablebases (22.5 gigs, just like I run on ICC) and so forth.

I have been noticing that I generally don't see less than 9 ply searches any
more, even in fast blitz games...
