This is either magical thinking or his previous computer was very badly 
configured or both. 

Every time you add a core the speed of processing can increase by no more 
than the speed of the added core. So a dual core can't be more than 200% 
faster than a single core. Claiming more than that can only be magical 
thinking.

In reality the overhead of managing two cores produces a gain of only 
150%. Adding more cores adds speed, but with diminishing returns. Rule of 
thumb is that a quad core, if all 4 core are really working, is 188% 
(100+50+25+13) faster than a single core.

Some even argue that a properly-tuned dual core can outperform a quad 
core for standard office applications. So buying more can actually get 
you less. There are also potential I/O bottlenecks that will slow you 
down no matter how many cores you have.

P.S. Frequently working "with multi-hundred MB graphic files" makes no 
sense. Anyone who does that does not understand the technology or 
software. A 24" x 36" 300dpi CMYK uncompressed TIFF would be 300MB. That 
is not a size frequently encountered.
