AFAIK, there have been mixed results which depend on which version of gcc you're running. While reading on the topic a few months back, the general consensus seemed to be that in general i686 (which is what I'm compiling with) actually resulted in slightly slower performance in some areas but this WAS expected to improve as gcc evolved. I think it also yields somewhat longer compile times, again this is expected to only improve.
In any case, I don't think there is noticeable difference in choosing either for most desktop environments. I think of more importance is the march flag (which I've got set to "pentium-m") which are supposed to include power saving optimizations.
