If it's gonna use 2 pci-express slots, for sure it's eating massive  
power, just like the gpu's.

Furthermore the word 'double precision' is nowhere there, so we can  
safely assume single precision.

Speaking of which - isn't nvidia and amd already delivering cards  
that deliver a lot?

AMD's HD6990 is 500 euro and delivers a 5+ Tflop and supposedly so in  

Knowing intel is not delivering hardware dirt cheap - despite  
hammering the bulldozer, bulldozer
so far is cheaper than any competative intel chip - though might  
change a few months from now when the 22nm
parts are there.

For crunching get gpu's - as for intel - i hope they release cheap  
sixcore cpu's and don't overprice 8 core Xeon...
