NVIDIA GameWorks Integration

Yeah, would be nice to know how fast one could meltdown one of these with GameWorks. Just kidding. I would like to get some clarification too, but for a different aspect.

It would be nice to know how well (or if at all) the current provided techs (WaveWorks, HBAO+, VXGI, Flex, HairWorks and Turbulence) work on different gpu architectures (, Kepler and AMD ones).
Some kind of table or rough explanation would be very nice, since I have no way of testing these techs across different GPUs. I only have my single 970 and nothing else, so getting a bit of light in the dark would be appreciated.
