Well first; technically the machine has tow GPUs not cards.
Second; The Intel GPU has access to system RAM which Mavericks dynamically allocates to the GPU. This is rather a dramatic improvement to Mac OS and should make for far more flexible performance from the integrated GPU.

This is actually a good question and the right answer is yes in some cases it can be an advantage. Maybe not so much because of more RAM but less overhead getting to that RAM. Some very interesting results are seen in OpenCL tests where the Internal GPU accelerates apps a lot more than maybe was expected. If you use OpenCL or apps that use it, the Haswell GPU, especially the Iris variants, may be a far better chip for acceleration.
Or is this just a stupid statement?
(My main use is Aperture)
Well for Aperture right now it probably doesn't matter. Mainly because Aperture doesn't strike me as being extremely accelerated to begin with.
Now that being said OpenCL acceleration of Aperture might work rather well on Haswell, I just don't have practical experience here to guide you one way or the other. Your best bet would be to find benchmarking sites that over these sorts of things.
