Notwithstanding the performance improvements you would notice by upgrading to more cores and/or faster base clock, are the integrated graphics benchmarks inherantly tied to the base clock speed? For instance, could I expect slight better GPU performance when using the 3.2 Ghz i7 vs the 3.0 Ghz i5? If so, would that mean that the GPU would generate the best graphics-only benchmarks when paired with he 3.6 Ghz i3?
