The recommendation for ProSeries professonal is a CPU equivalent to i5 at 2.5 Ghz.  That really doesn't define what's needed.  There are multiple i5s, multiple generations, cores, etc with various processing power.  Far more useful to judge (swapping from my All-in-one to a desktop as AIO CPU Ghz are a bit more limited) would be a recommended benchmark or single thread rating? 

@@Anonymous would you be able to ask the tech people this?

Thanks!
