Does nVidia itself makes Graphic Cards? or only GPUs?

nVidia does not actually make the graphics cards; they make
the GPUs, which are then integrated with cards by 3rd-party resellers.
According to the nVidia rep, even if they show the nVidia name, the
cards are *always* from another company, such as MSI, eVGA, or PNY.
I can attest from my own experience that the identity of the 3rd-party
company is not always easily discernible by inspection of the box or
the card.
(Note that when purchasing a video card, you need to determine whether
your system requires a AGP or PCI-E card interface:
from t-break: PCI-E Bandwagon, you can see a picture showing both
types of card connectors:

Other products made by nVidia include MCPs (media and communications
processors) and AMD chipsets for motherboards.

What processor is this?

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.
