The processing power of the GPUs are not automatically pooled like that on a mac. How you benefit from multiple GPUs is instead dependent on the application you use. Some might let you pick which GPU to favour, some might let you run multiple computing jobs dispersed on different GPUs for a speedup but again, it all depends on the application in question.
I think you are most likely to see CUDA or OpenCL applications benefitting from extra GPUs. That is also supported by your own measurements in LuxMark.
You can see some examples of benchmarking in this (now somewhat old) Barefeats article:
