Yeah, that's basically what I'm getting at. Ryzen 9 is outside my budget at the moment, so I was mostly wondering if it's even worth upgrading. Nothing seems to be choking out at 100%, and my thermals are decent considering I'm just using the stock cooler (doesn't usually get above 80 degrees on the CPU).
I may upgrade anyway at some point, just as an excuse to throw the old parts from my current PC into my kids' computer, which is running a Phenom ii x6 (yes, I know I'd need a motherboard too...but it's a kids' computer, any cheap am4 board will do.)
Thanks for your input!
