Who knows?

100 mostly idle users doing small optimized selects is a far cry from 80 
users with rapid response requirements doing a constant heavy stream of 
inserts and updates to tables with multiple indexes and foreign-key 
constraints while the other 20 are doing large reporting and analytics 
queries. Both use-cases match the above description.

To get a useful answer you will need to provide lots more detail about 
the nature of the workload and expected responsiveness.

Cheers,
Steve
