Yes we have a lot of those over here. But i get the impression you do not.

2600k is just a 4 core chip and expensive. Not interesting therefore.

Only a very old machine mine has 4 cores. It's from 2005.

Watt meter here proves you wrong.

HD 6990 is of course the king everywhere. 1.4Tflop double precision and 5.4 Tflop single precision.

As most codes i run are not capable of multiply-add, you can from *all* manufacturers divide that capability by 2 by the way.

As you know the GTX590 is crippled in double precision by factor 4. So it has just 25% of the double precision capacity of tesla times 2. meanwhile you pay a big price for the GTX590.

It's fast for 32x32 multiplication.

Yes you just can google and over here we test.
Thank you.
