If you currently have a desktop PC, then there will be no problem.
If you have a laptop, then there could be a problem...
1. Many laptops have the CPU (APU in this case) soldered into the motherboard.
2. The laptop may not be able to handle the heat output of the more powerful APU.
3. I'm not sure if both desktop and laptops uses the same FM1 socket. A mobile Llano APU might use a different socket.
