When i started setting up the scripts i experimented with the GPU-VMs from Azure. The GPU of course is capable of a higher hashrate, but it is also more expensive. I found that in the end the profit is approximately the same, but setting it up is by far more difficult. For the GPU to work i have to install some external NVIDIA CUDA-packages and reboot the VM a few times. Setting it up was a fight even with the official guide from azure.
I checked the hashrates you gave at whattomine.com and it did not show a higher profit than Monero (assuming 1600H/S), even if you take into account the extra 6 CPUs. I know profit-calculators are not really exact... do you think that the numbers are so far off that in the end using the GPU would yield a better result than CPU-mining?
