Alexanderherman,

 

To start off:

 

1. What is the designation of the current processors ?

 

2. What are first and second priority applications?

 

Which will inform the choice between:

 

A_ Powerful = Core count (= total clock cycles per unit time)

B_ Fastest = Single Thread performance  ( = highest clock speed)

 

There are good compromise CPU's that have both quite a lot of cores  e.g. 14-18 and a healthy top clock speed : e.g. 3.6.-3.8GHz

 

3.  How much RAM?

 

and:

 

4. What is the boot drive?
