thanks for the information, but you really should (also) use the latest gcc 
(3.3x) for such a comparision. It will be interesting to see how it performs 
relative to the latest icc on the one hand, and to the old gcc on the other 

And some information on the application (or libraries used) would be helpful, 
too. Like: is it memory-bound or compute-bound, etc..
