Im trying to find out more, cousin works for nviida, she told me about htem a week ago, and people are talking about them all around in ZCash groups in china now... when i find out any more I will update.
Otherwise I think it would be smart to wait and see... i dont think they they will be overpriced if they are aimed at miners and mining farms.. else why would they make them... ?
There would be no point in making a mining specific card that does nothing else but mine ... and then charge more than the gaming cards... no one is going to pay more money for less hashrate per dollar invested in the GPU.
Nvidia doesnt like miners using their mainstream gaming cards for mining, they do not like dealing with warranty issues on the cards, so instead of fighting it, they are starting to embrace mining (as far as I can see).
Even if they do end up costing 2000 or 5000$ a GPU, if the hashrate is worth it and makes it a better buy... then it is a better buy... and if they are coming out with these cards... we should wait to see if these cards will kill the current hashrate on existing GTX cards.
I just dont think its smart to build a GTX miner without knowing more about these cards, as they will be coming out ... so...
