It's hard enough for me to piece together the capabilities and
limitations of processors, cores (real and virtual), OS support, 32-or
64-bit, hyperthreading and the way all that relates to licensing
conditions, but then having to pick apart the fractal layers of CUDA
capabilities makes for a pretty complicated puzzle.

I think the Wikipedia overview articles on NVidia GPU families is
pretty good, and the tables describing layers of CUDA capabilities at
least give some insight into the types of questions to ask when
documentation examples don't work for you.

True, none of that forms a basis good enough on which to order
expensive hardware, but it can help with the shopping.

I'd like it if WRI would post an authoritative guide on all this with
emphasis on how Mathematica interacts with it. I think WRI isn't the
type of company that would certify particular configurations, but we
could hope.

Bummer about the new MacBookPro going to AMD Radeon graphics.
