I'm afraid the only answer we can give you is 'that depends ...' :-(

Three most important things you need to know before answering the
questions is;

1) dataset - How much data are we talking about? Is only small part
   active? Is it static / does it change a lot? Etc.

2) workload - Are you doing simple or complex queries? What portion of
   the workload is read-only?

3) hardware - CPUs, drives, ...

There's no way to answer the question without answering these questions
first. There are databases that promise you everything without asking
you these questions - treat them just like Ulysses approached sirens.

I understand these questions are difficult to answer before the project
even started, but you certainly have an idea how it's going to work so
do estimates and review them as the project progresses.
