just about no one buys those cause they cost at least $500 and there all the older newcastle cores too. too close in price to the fx53 as well so people just took the fx53 instead. whats the point even? just get a fx53, you can get one used for $600, maybe even $550 if you look around and ive seen those do from 2.55 to 2.7GHz on air cooling. fx55 is $850-900 but generally add 200-300MHz ontop of that so 2.75 to 3GHz on air. a great deal is the 3000+ winchester, you should get a retail one for mid $100s, or in the 150s to 160s mine does 2.6GHz which is honestely almost as good as a fx anyway minus half the cache, but losing half the cache does NOT mean losing half the performance, try 10-15%
