if you run at least 2 CPU-intensive processes in parallel - yes it's 
MORE THAN 4.4Ghz performance equivalent.

why more? because when processor gets stalled at memory access (memories 
are still 45ns at most), throughput is halved not stopped.

in unix environment bunch of slower processors are always better than one 
fast.

my ONLY home computer is IBM/Lenovo T23 laptop with celeron 1200 and 256MB 
RAM. it's really enough
