My friend bought this for his first build, except I supervised him. And ended up taking over. But that's not important right now.
I advised him to buy this processor, why? It's on an outdated socket and only scores similarly to a Phenom x4 955/Intel i3 2100. However, there is a reason. These processors are built as 6 cores and have the extra cores disabled - he managed to get an unlock out of it (and a stable one, at that). If that's not enough, we then got the six cores to 3.6ghz on stock voltage! Sadly however, we couldn't find the voltage in BIOS...
Cooled by a Corsair A70 (which was a personal recommendation from another friend due to good cooling, value for money and easy installation), the temps never went above 38. That's with all cores unlocked at 3.6ghz while running Prime95 for half an hour, so if left on all day at full load I'd expect 45?
Very good processor, I've been genuinely impressed and tempted to buy one over my own Phenom x2 555 (unlocked).
Also, if anybody is wondering what board was used, it was an MSI 880g one. I am not too sure of the model, sadly, but it was fairly cheap.
