Finally a confirmation on this card

GTX 1080 Graphics Card | GeForce

it looks like an absolute beast and not overly expensive - looking forward to trying it. is there any reason why it wont be supported in PR?

Cheers

Gareth

    I wonder what computer specs will justify using a card that powerful?

    I am looking forward to what Eric Bowen will have to say about the minimum necessary CPU required to push that 1080 to its potential. I watched the NVidia live stream event and was impressed at the claims of massive performance increases along with energy efficiency.

    I am guessing that the flagship Broadwell E will be a good match !! NVidia is touting at least a 30% performance increase over Titan X at far less wattage AND cost !!  They also claim " insane overclockability".  The 9xx series Maxwells did not allow much overclocking.

    NVidia claimed a stock clock speed of over 2,000 Mhz and over 5,000Mhz on the memory clock speed for the 1080 !!...all with 8 GB of blazing fast new DDR 5X memory !!

    I have to laugh as my not too shabby Asus gaming laptop GPU sports 2GB of plain DDR5 video memory and even overclocked to the max is running at 915 Mhz clock speed and 3,000Mhz on the memory clock speed !!...( stock is 700Mhz and 2,000 Mhz, respectively ).

    This new possible CPU and GPU combination on the X99 board is going to be powerful.....no need for multiple graphics cards.

    I've seen some benchmarks on the 6950X Broadwell E flagship CPU done with engineering samples and the results indicate a modest performance gain over the 5960X Haswell E flagship CPU of about 10% in multi threaded tasks. Its too bad that the Broadwell E will NOT be offered at a decent price, like NVidia is doing with Pascal. Intel will get an extra $500 for 2 extra cores and a slightly lower clockspeed with overclocking.......only 4.2 to 4.3, so far on the engineering samples. $1,500 for a Broadwell E is going to hurt !

    I hope Eric tests this new combination soon ,like he did with Haswell E and posts the results on this forum !!

    I am hoping that this is not another CUDA limited product like the Maxwell cards are.  Maxwell cards fall back in the memory clock as soon as you run any CUDA application.  Power Consumption is a major goal for nVidia and CUDA took a hit with Maxwell so for all the great specs for Pascal we will have to wait and see on this new GTX 10 series if the samething happens

    Also note that you do not get this new great performance memory on the GTX 1070.  The quoted 10 Gbps on the GDDR5X memory is only on the GTX 1080.  The GTX 1070 only has standard GDDR5 7 Gbps memory.  With my GTX 970 rated at 7 Gbps when you run any CUDA application it falls back to 6 Gbps.
