Right, but we weren't talking about the AMD.  The difference in price is 
that the AMD and it's -true- quad cpu is that the AMD starts at over 
$1,000 wholesale.
The stripped down, celeron version of it is the heart of this 
discussion, and it's ~~$330

I'm, just repeating what I was told by someone who works in the 
industry.  The millisecond a 64-bit cpu sees a line of 32-bit code, the 
cpu reverts back to 32-bit
