What is difference between Core 2 Quad Pro and Core 2 Quad

[Bidybag]

I found two versions of the same processor and the only difference i see is that one of them is 95W Energy Efficient. Is this the only difference? The names of the two products are:

Intel CPU Core 2 Quad Pro Q6600 95W Energy Efficient 2.4GHz SLACR G0 Stepping

Intel CPU Core 2 Quad Core Q6600 2.40GHz 1066FSB LGA775 8MB cache (4x2MB)
link: http://www.microdirect.co.uk/(16406)Intel-CPU-Core-2-Quad-Core-Q6600-240GHz-1066FSB.aspx

Please can you tell me why there is a another version of the same processor and if one is better than the other?

Get the first one , because the first one runs cooler and will OC better

Some retailers use the Core 2 Quad Pro as short for Core 2 Quad Processor.

Intel® Core™2 Quad Processor Q6600 is the official name, thus the similarities.

Nonetheless,

Intel® Core™2 Quad Processor Q6600 "G0",

is better than

Intel® Core™2 Quad Processor Q6600 "B3",

Thus,

get the

Intel® Core™2 Quad Processor Q6600 "G0",

How come the better one is less expensive?

Because the production of the B3 version was stopped and was replaced by the G0 version. There's not much supply of the B3 version, so price goes up.
