"In the AMD world, the 5000+ Black Edition should be on your short list if you are looking for a quick overclocking fix, or upgrading from your aging 939 system and not ready to take the Phenom plunge, but secretly hoping it will magically pull performance out of its hat. With the 65W TDP of the CPU, the Black Edition would be right at home in an HTPC where it wouldn't break a sweat, and you would have the ability to crank it up a bit to get your game on. At stock speeds, the 512KB of L2 Cache on the 65nm Brisbane core seems to hamper the performance of the CPU when compared to its older brothers, the 6000+ & 6400+ on the 90nm Windsor core, but it has them both beat in power efficiency."
