Calculate this for me? Diffraction limitation.

Assume that the sensor is 44 x 33mm and captures 100MP, and that it's paired with a perfect lens.

At what aperture setting will diffraction limitation reduce the effective MP value to 75? And what setting for 50 MP?

I'm trying to determine whether a certain upgrade will bestow substantial gains.

Thanks.
