[SOLVED] Which one is better for PC? Between having only discrete graphic card and having both discrete and onboard graphic card?

I have a plan to have a new PC and I have a question. Which one is better for PC with a single monitor? Between having only discrete graphic card and having both discrete and onboard graphic card?

If you have a discreet GPU, that one will be used all the time.

But, also having the onboard (in the CPU) can be good for troubleshooting.
