This makes no sense and I'm guessing the scan/employment is entirely fake and setup to sell computer equipment.
Today MHz on a processor is an irrevelant number. A quad core i5 at 2GHz does more than double the processing work on a task than a pentium G2180 (also clocked at 2GHz).
While in theory you migt be able to overclock the CPU, something seems off about the employment... and as I've never known minimum system requiremts to run the program very well - even overclocking your CPU would still make their software run horribly (if it needed the 2GHz+ spec)
