Specifically of Biophysics, with IP over 5, you have the Annual Review of Biophysics, some areas of Biophisica et Biochemica Acta. And others more generals as PNAS, for instance.
But, in general, there are very good biophysical journals with a IP range between 4 and 2: Langmuir, The Journal of Physical Chemistry B, Biophysical Journal, all the BBA journals, among others. It is only my opinion, of course, but working in biophysics, I have been reading very good works from these journals.
