Oups ! I mixed up in my answer : non SSE2 code is slower than SSE2 code, I think the iteration times with SSE2 (and thus bigger FFT size) would be smaller than without SSE2 (even with the smaller FFT size.) Like AXN1 said and I suggested to be sure you have to benchmark it if you want a definitive answer for your computer (memory speeds and chipset have some influence as well.)
