Short description of error
In official Blender 2.79b I can see my graphics card and use it for GPU rendering with CUDA... In newer versions it doesn't work anymore. Blender just says "No compatible GPUs found"... this has been happening for months now in newer versions than the official 2.79b, I just hadn't the time to report it until now, sorry.
