no, it is a gaming first design and Nvidia would rather you buy a quadro card for professional work.
unlike the 570 and 580 that were very powerful for CUDA the 680 and other kepler designs will have a lot less relative power for GPU computing compared to the older much less power efficient fermi designs.
they made the kepler chips extremely efficient the kinda of loads games put on a GPU but pure compute power is really never used in gaming and as opposed to furmark or folding no game will ever really peg a GPU so Nvidia focused on gaming performance and by doing so cut the power requirements a huge amount and still made a card that is a good deal faster than their prior models.
That said, almost all "video editing" is still done on the cpu and there is nothing that specifically makes the 680gtx "bad" for video work it is just that currently the hardware h.264 encoder isn't much different that what intel Sandybridge has already and Ivybridge should be better than that too.
Nvidia will probably stick with a GPU compute focused design for the professional markets separate from the gaming focused kepler for those people that need the GPU computing power or things like SDI outputs and the like and odds are if you are only hobbiest level encoding a HTPC card and a fast intel chip will encode anything just fine without the need for specialized h.264 encoding engines or trying to use mediaspressio.
