[mythtv] OpenGL developments

Number of shaders, vectors, etc is all to do with 3D rendering, and it aint
gonna help much with 1080 decoding. In fact, most of the value of this card
is in it's 3D capabilities, and you'll probably find most cards supporting
XvMC will have similar capabilities. The key is to make sure it will support
both MC and iDCT to take full advantage of the decoding, and check it's
fully supported by myth.

OK so sounds like this is more than possible, when picking a card,
should I go for the number of shaders or the some other variable
(clock speed maybe) to give me the best chance of offloading 1080p?

I am thinking the Nvidia 8xxx series.

Is there anything the community can do to help, donations?
