Once someone writes an implementation, we'll be able to tell you which 
specs are important...  ;)

Definitely overkill in the short term and a bit of a gamble--i.e. is the 
extra cost of buying near-top-of-the-line now less than the cost of 
buying a sufficient (i.e. NVIDIA 5200 or so) card cheaply now and buying 
again in 1, 2, 3, or 10 years (getting the 3-year-old, then middle-tier, 
but now overkill NVIDIA 8,600,000) once someone makes it possible to 
take advantage of the card's power.

And, quite possibly, by the time someone writes this code, 
general-purpose CPU's may chug along downclocked to their lowest 
stepping when decoding 1080p60 MPEG-4 AVC (H.264), making the use of the 
GPU for decoding about like using XvMC--or worse, a dedicated MPEG-2/DVD 
decoder--for decoding SDTV today.

Note that I'm not saying don't buy it--but neither am I saying to buy it.

I doubt the community would be interested in donating to help offset the 
cost of your purchase.  ;)

Seriously, someone just needs to write some (good foundation) code so 
the snowball can begin rolling and picking up more snow...
