Couldn't for the life of me, figure out what was going on with my CPU. Tried everything I could think of, but no luck. After some back and forth and a few DMs, too, this sub got me squared away and the PC is finally running like it should be. Pic is a before (left) and after (right).
A lot more tweaking to be done, time to see how far I can push the rig.
Appreciate y'all a bunch o7
