problem is, it's pretty hard to find one at a competitive price, since AMD pretty much end-of-lifed it when the FX-53 came out, rather than shifting it down the lineup. If you're looking for overclocking, the 51 just isn't gonna cut it any more. It tops out at about 2.4GHz, which is not that impressive. The stock specs are equal to a 3400+, which is around $230. In fact, the $140 3000+ and $190 3200+ (socket 939) can both overclock to 2.6GHz, so it's a far better choice, being substantially cheaper and not requiring more expensive, slower registered DDR. Unless someone is just giving it to you, it's pretty pointless to look at one.
