    Re: Nvidia GTX 680

    In the 680, it's a physical reduction of FP64 cores, which are then additionally crippled. Nothing can be done.

    In the 400 series and 500 series i never found out how it's done for sure, but i DO know it isn't done through BIOS. So hacking that won't help at all.

    It's possible it's done in the drivers. If that's true, the last driver release that wouldn't've been crippled would've been during the reign of the 200 series, however, conveniently enough, those drivers won't allow a 400 or 500 series card to work at all.

    Dude, you are the man with the info! Unfortunately it is not real positive info, but it is the truth none the less. OK, well that means for high end crunching I need a high end AMD card next I suppose. We'll see what I can come up with...maybe nothing, we'll see. This whole thing still blows in my mind. They get us sooooooo excited. For...NOTHING.

    Re: Nvidia GTX 680

    Yeah that how im taking it also .. Im assuming the worse, they didnt want the 680 to compete with the quadro whatever its called. Either that or it was a way to reduce transistor count on the chip making it cheaper to produce and yet still do extremly well in games. We can hope they release something better later on but im guessing at this point. The good thing is this will force AMD to lower the price and soon. So be patient it will happen and you will be able to save 100$ on the 7970 if you can wait..

    !! <---That was so i could meet the 2 character minimum message limit. Quotes don't count. Grrrrr

    EDIT: actually i would like to add a few more characters. How do such incompetent f__kwits, people so GD retarded they think cheerios are donut seeds, get the jobs they get while people like me sit here counting the number of empty Dr. Pepper cans on my desk? Makes me want to pull (the rest of) my hair out! [/rant]

    The whole thing just stinks. It's one thing not to have the technology period. It's another thing for that technology to be "present" but out of reach financially to all but giant corporations or Gov entities such as NASA. It is quite another thing altogether for the technology to be present, and financially accessible...and then denied the consumer because of stupidity and uber greed on the part of the corporation who makes it. I'm not against them making a profit. I am against them scalping me because I want to use the CUDA portion of their technology whch EVERY ad of theirs boasts about.

    I think my next GPU may have to be an AMD just for the principle of it. Is the 7970 turning out to be that hot of a card on Moo! or Donate or whatever the hot AMD/ATI project flavor of the month is?

    I thought I read somewhere it was a firmware/driver imposed limitation as nVidia didn't want to muck with fabrication layouts or some such thing. That is for pre-680 units.

    Edit: For anyone that has not seen the "Pro" units ----> http://www.nvidia.com/object/workstation-solutions.html
    Their top shelf card sells for $3,998.00. Now you see why nVidia limits the 680! For x8 the price you get your card unlocked..........

    Gotta admit that really looks awesome. Too bad they wasted all that effort on Nvidia And only 7dB max fan noise. I'm figureing that doesn't count the radiator fan, only the one on the card.
