The processor is good, and runs great, but be mindful of the watt requirements of the processor. Even if your motherboard documentation states the motherboard supports that processor model 955, there are 2 versions of it. The 125W and the 95W processor. My motherboard only supports the 95W processor, so this specific processor worked, but very slow. In the end, I traded it with a friend for a slower processor that runs at 95W.
That was my mistake (so no negative ratings), and if you plan to buy this processor, check your motherboard website for the watts supported by the motherboard.
Other than that, the processor runs great, and is very fast. At least it runs great on my friends computer, and he likes overclocking. He's really happy with 'my' purchase at least.
So the product is good, but be mindful of the watts required and do not make the same mistake as me.
