Hi my friend asked me to upgrade the cpu in his laptop as he wants a more powerful one. he is not sure of the model of the laptop besides that it is HP. He sent me a screenshot of what the CPU is. The CPU is AMD A6-Series A6-4400M. Can someone reccmond a new CPU and somewhere i can get it at not a bad price. I live in Australia so the store needs to ship to here of course. Look forwards to your replies. Thanks in advance
