Yep very good deal, if you are just going to use the computer for routine software, etc. It is not adequate for a first class gaming machine.
It was not that long ago that it was the best CPU out there for the money.
Be sure you have access to a working motherboard for it. Fans, thermal paste, and heat sinks need to be researched so you know your total cost.
Make sure you know what your buying on ebay. I was looking for a specific AMD cpu and on 3 seperate items the product description was in-correct and I wouldn't have been able to use it.
Note the heat sink carefully to be certain you have retainers to hold the heat sink firmly to the cpu and the motherboard. These clamps are critical, and often one set of clamps do not fit other heat sinks. Getting the correct fit for used stuff is often very difficult.
Your existing clamps may work just fine if the heat sink is the same size and shape, but others may break, or damage the retainer on top of the heat sink.
