With compute performance below that of the AMD cards and previous generation nVidia cards, my bet is that people who run BOINC will shy away from this card, or somewhat begrudgingly buy this card because of its power profile.
nVidia's tack with this card of protecting the workstation and Tesla cards, which they have every right to do, may push customers away. I'm, for one, will not spend big bucks on a pro card since I am a casual user. Given this card's price point, I was considering one even though it's price is above what I would normally consider acceptable. Now that I know that compute performance may be on par with my GTX 460, I may opt for one of the Radeons instead.
IMHO, a better tack for nVidia to take would, instead of the high-end WS cards for great compute capability, let the consumer cards handle it. For the same amount of money, they would likely sell whatever number of consumer cards that would add up to the cost of a Tesla. GTX 460 compute performance exceeds that of C2070s in some cases.
Obviously I am not happy about the decreased focus on compute performance. I recognize that it is their right to do it, however, I think they are forsaking a market segment and it may end up backfiring on them.
I'll be waiting a few more months for my build, and hopefully, they will release a consumer card that has compute performance more of what I was hoping for. It would be interesting to know if nVidia has announced any plans for cards with better compute performance and what market segment they hope to target with those cards.
