I would, but I can't, because AMD dropped support for OpenCL in their driver for those old cards.

Yes

Not much but a bit, yes

I think they only care about CUDA and I'm not sure they have a proper OpenCL implementation for their cards.
It changed with maxwell, they show very good OpenCL performance
