Hello @ktaylor4321
Well, it depends on your motherboard and to be honest how much you're willing to spend (both time and $$$).
Something tells me your motherboard features an FM2+ Socket. So, any FM2+ later-generation APUs will do the trick. That said, I suggest you consider the time and effort you'll have to put into this upgrade since the APU/System is about 10 years old.
