To answer the last part of the question - it is definitely the quality of the
engine that defines the strength of the program.  The RAM affects the strength
but only by +/- 100 ELO at the most.  CM6000 is The King engine that is extremly
strong at tactics, which is why it solved your problems so quickly.
