When _calculating_ peak performance on Xeon it is usually assumed
that two Flops can be performed during one clock step
e.g. http://www.top500.org/sublist/System.php?id=7293
(although in practise it is rarely the case).

The easiest way _measure_ peak performance on the Intel platform is probably to check 
which will make you going.
