Hardware advice

UPDATE:
Sticking with the original thread for history.  I purchased an Intel ARC A310 video card and installed it. It seems to be working fine BUT when I run Handbrake, my main CPU usage still maxes at 100%.  @TheDreadPirate had mentioned that my audio would still fall back to my main CPU. Just out of curiosity, I set up an encode with no audio included and still, it maxed the CPU and didn't raise the usage on my new video card at all.

This could be just a holdover that the computer is too old but I wanted to check here first. Shouldn't the video card be handling all of the Handbrake load now?

(Yes this might a Handbrake question but I'm hoping that the people here might be more familiar with it. lmk if this is not allowed)

You need to enable QSV support in the Handbrake settings.
You also need to select one of the QSV GPU encoder options in the video tab.
