From a theoretic standpoint, attic temperatures are inconsequential.
Where attic temperatures create issues are for homes with zone HVAC systems in the attic, ductwork, kneewalls, etc.
All of those scenarios overly stress what are inadequate insulation levels on vertical kneewalls, around ductwork lines, and the air handler itself.
A radiant barrier stapled to the underside of the rafters/trusses is a well proven application and seems to work quite well in these scenarios.
