If it could search that deep in 2-3 minutes it would have a good chance against
DB.  DB was roughly 1000 times faster than the best single-processor CPU of
today...  maybe a bit more when you factor in evaluation...  Instead of 3
minutes, if you could search 3000 minutes it would be in the right ballpark.

But that is a long way off of course. :)
