    Yeah gamers really need to own both NV and AMD products in order to win with PC gaming. It sucks but that's the result of the devrel money games and occasional developer NV preference (usually related to NV devrel being more helpful).

    To be fair to Cryptic, the DX9 mode seems to prefer AMD, and Champions Online does as well.

    Was there ever a proof of paying anything?

    I think there was with ati and hl2
    and those intro videos with runs best on core 2 and best plated on nvidia I cant imagine the dev added them for free
    not quite the same but nv stated to devs they will port their physics to physx for free

    Money did switch hands between ATI & Valve, but the question remaining is wether it was about devrel/better support for ATI, or for the fact that ATI got to bundle HL2 on everything (even if only as coupon due all the delays)
    IIRC in HL2 there wasn't really anything "ATI specific" though, just the fact that GF FXs were so horrible with FP32 which was used since FP24 wasn't available, and FP16 hints weren't used apparently at all (they were eventually rewritten by fans to work fine, but if my memory serves me right, outright just switching to FP16 resulted horrible artifacts, and the shaders had to be rewritten for decent results)

    FP24, one has to remember, was the standard full precision before SM3.0 required FP32. The only question is would Valve had added FP16 _pp flags if ATI hadn't been involved at all in any way

    They had fp16 shaders before release.

    I can only imagine how quiet that would be... so I'm impressed

    A bit late to the thread but just thought i'd add my opinion. The 7970 performs quite well no doubt, but as most people have already stated, its price leaves much to be desired. Of course compared to the GTX 580 it is priced well. But after AMD's previous flagship single GPU cards all released below $400 (4870 at $299, 5870 at $379, 6970 at $369) it was unexpected. I guess everyone expected AMD to continue the trend and play the value card.

    I really think AMD would have got a much better reception if they had launched the 7970 at $499 instead of $549. While the difference is only $50, psychologically it appears to be a far larger gap than it actually is. And ff we take actual manufacturing costs into account, i doubt it really costs them $200 more to make a 7970 than a 6970. Its not like AMD's gonna be making a boatload of money either given how low the sales of the top tier GPU's are. IMHO it would have served them a lot better in the long run to price it well and get some positive PR instead.

    I expect the prices will play out as follows in the next few months

    7970 3 GB - $499
    7950 3 GB - $399
    7950 1.5 GB - $349
    7870 2 GB - $249 - $279
    7850 1/2 GB - $199 - $229
    7770 1 GB - $149 - $169
    7750 1 GB - $129 - $149

    Sorry i guess i missed it, pissed about what exactly?

    Sapphire toxic edition clocked at 1.35Ghz should bring it up to a 6990, At 1.2Ghz it gets close but 1.35Ghz should do the trick.

    Tri-Fire and Quad-Fire configurations with these are CPU limited, Even when running 5Ghz+ Intel CPU's.

    Has this card been confirmed, or is it still just an entry on a possibly real leaked data sheet? I'm still having trouble believing that such massively overclocked SKUs could be released.

    I'm guessing with enough binning they could release a limited edition card with that OC.

    It's not uncommon to see reports of 7970's at stock voltage hitting 1200-1250. So with aggressive binning, it may be possible with only a minimum voltage increase.

    And of course, if it was around 6990 levels of performance it'd command a suitably high price reducing demand such that it can be a high margin low demand product.

    All theoretically, of course. I'm doubtful as well that one will come out in the near future, or possibly ever. I think "Super OC" cards in the 1200-1300 range will eventually come out.

    Regards,
    SB

    That's clearly the Eyefinity version with 6 x Mini-DisplayPorts :)

    I assume the WC stands for water cooled but I don't know what RX is for. Maybe a really high binned chip with custom air cooling and custom PCB?
