Great upgrade - lots better than replace the whole computer.
I upgraded from A4-6300 CPU and it shows great improvement. I no longer have CPU usage of 95%. I think this upgrade will last me another 3 - 4 years. It was worth it.
Runs a bit warm, but otherwise was a good upgrade over the A4-5400 that was previously in my nas. The A4-5400 heatsink was not enough for to handle the A10-8750 so I ended up buying an artic 7 cooler which is working great on this processor.
