PPro CS6 Only uses the Mercury Engine Plus new PC specs

I’ve looked into preferences> General to see if I can improve my system/application performance.

 

It is set to the: Mercury engine, software only.

 

It’s kinda greyed out and won’t let me choose to us either GPU (CPU?).

 

Question 2:

Could you please describe a configuration for a new PC that will meet the needs of CS6 Suite without breaking my bank?

 

I neet it to be a notebook for mobility.
