Hi Marek,
It 'should' work with the new driver and 7.5 on the GTX470s - NVIDIA does deprecate GPU support in newer drivers but this tends to be after many years or for very low end models, e.g. NVS200. My guess would be that you should be fine to just switch to the new driver and everything to CUDA 7.5.
All the best
Ross
