Yes (3 months ago). Setting up opencl on AMD card on Ubuntu is a nightmare for me (I have done it 3 times over the past 2 years, and failed 1 time).
Recently I setup CUDA on Ubuntu (with an Nvidia card), and everything just worked.
(I'm using the manufacturers' drivers).
The difference was amazing.
I get the distinct impression that Nvidia try hard to make things work easily for you, whilst AMD just do not care (at least for Linux).
Relatedly, AMD's website has an 'OpenCL Optimization Guide' [0] (which you really need in order to use your GPU effectively) - for 2 years now, it has been out of date by 1 year or more, not updated to discuss the latest hardware.
