Yes, purchase a new laptop that is still supported by AMD.
You can find out from your Laptop Manufacturer if they have a more updated Mobile Processor that you can replace that will work in your laptop and is still supported by AMD with updates. But the cost probably wouldn't be worth it.
Since you have such an old legacy laptop it is best just to purchase a newer supported laptop if you can afford it.
Besides, your APU is just to old and weak to be able to play today's modern games correctly even if you had newer updated Graphics driver.
