david...

What you have is a model FX-55, 2600Mhz, Socket 939 processor,
as detailed on this page from AMDcompare:
http://www.amdcompare.com/us-en/desktop/details.aspx?opn=ADAFX55DEI5AS


The two best places to look at the current value are:

Pricewatch:
http://castle.pricewatch.com/s/search.asp?s=AMD+FX-55

eBay (don't look at the bid figures, but the BuyItNow prices):
http://search.ebay.com/search/search.dll?sofocus=bs&sbrftog=1&from=R10&satitle=AMD+FX-55+processor&sacat=58058%26catref%3DC6&sargn=-1%26saslc%3D2&sadis=200&fpos=ZIP%2FPostal&ftrt=1&ftrv=1&saprclo=&saprchi=&fsop=1%26fsoo%3D1&coaction=compare&copagenum=1&coentrypage=search

So, around $200-230, and more, if you have the AMD box with 
the Box Fan and Heat Sink, and 3 year warranty.

When I visit:
http://castle.pricewatch.com/s/search.asp?s=AMD+FX-55

I see that the prices have a wide range. Some are listed as high as
$1500. What is the reason for this price difference?

The item for $1430 is a computer that is built with the processor
as a component. As for the ones listed at $899, this is the CPU
plus the box fan and the heat sink in the original AMD package
with a 3 year warranty, such as pictured here at SpartanTech:
http://www.spartantech.com/product.asp?orderid=55878786094121950864790&PID=AMDA64FX55BNBOX

Also notice the part number ADAFX55BNBOX on these listings, vs
ADAFX55DEI5AS. The former is the AMD Athlon 64 FX-55 San Diego
2.6GHz Socket 939 Processor, as can be seen in the images of
the CPUs on some of the listings on eBay. The latter is the
AMD Athlon 64 FX-55 ClawHammer 2.6GHz Socket 939 Processor,
as can be seen on this listing from Newegg:
http://www.newegg.com/Product/Product.asp?Item=N82E16819103492&ATT=19-103-492&CMP=OTC-pr1c3watch

They're both AMD Athlon 64 FX-55 2.6GHz Socket 939 processors,
but the San Diego is version 1.2.3 of the 1.2 Athlon 64 FX
series, while the ClawHammer is version 1.2.2, as can be seen
on this Wiki page:
http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors

You can compare the two on the same page, at this link:
http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#.22ClawHammer.22_.28CG.2C_130_nm.29_2

With its slightly lower operating voltage, the San Diego is
more desirable to the overclocking crowd.

The newer San Diego version supports SSE3, which is explained
on this Wiki page:
http://en.wikipedia.org/wiki/SSE3

Since the ClawHammer has been around for longer, the price on
PriceWatch is more stabilized, and $139 is probably a more
realistic low-end price for the CPU. On the other hand, for 
less wary buyers looking for a AMD Athlon 64 FX-55 2.6GHz
Socket 939 processor without regard for the version number,
$200 is not an unrealistic price for the ClawHammer. Not
everyone knows to look at PriceWatch for the lowest available
price.

For example, here's a Froogle search for the ClawHammer that
shows results for the unboxed version at between $140 and $222:

if it truly says "assembled in malaysis", i think you've been robbed.

Interestingly, there is a reference to 2001 in the information
provided, by the 64 but architecture did not come out until 2003.
Thats a little wierd.

That's when it was copyrighted. If you look at the images of
the back of the chip you'll see 2001.
