Pricing

Since the QX9770 belongs to the Extreme Edition line of processors, we can say with almost complete certainty that it will cost $1,470 or more. We also expect the QX9770 and QX9650 to be sold alongside each other for a while, since upgrading to a new (X48-based) platform is not attractive for buyers, especially considering the non-existent performance benefit. On the other hand, since both the platform and the processor are aimed at the enthusiast crowd, which is traditionally willing to pay higher prices for exclusive components, we expect that the QX9770 will initially sell at a higher price than the QX9650.

Intel is in an excellent position. The Core 2 Extreme QX9770 is not yet available, and the performance of AMD's Phenom processor is still an unknown quantity. This gives Intel some time to make a final decision regarding the retail price.

Due to the uncertainty it entails, we don't see paper launches (or pre-launches, if you prefer) such as this as helpful for the buyers. it is unlikely that a paper launched processor such as this will change anyone's buying decision....

    I am not sure why you are not mentioning the cooling system you use.
    Also why you don't mention that this processor needs water cooling system even if not over clocked.

    Looks like a Zalman fan to me in the pictures so maybe water cooling is not needed, at least for those not into cases (something I typically consider "benchmark machines" and was surprised by the lack of dry ice. By the way thermoelectric, chilled water, cooling using peltiers can't be beat! Finally I have a QX6850 and I get a 3mdMark06 of 18,548 with a Gigabyte EX38-DQ6 and a Shappire Radeon HD4870 X2 2gb (using not yet anywhere near perfected drivers) and without overclocking the GPUs until a water block is released for it. I was going to upgrade to a QX9770 now that I can pick one up for a good price since the 9775 came out but since reading that the difference in speed is not incredible I have decided to wait for the new Core i7 or whatever they call the new extreme processor and motherboards with new sockets coming out soon.

    To show the QX9770 overclocked alone is bias as I run my QX6850 overclocked. When compared to the QX9770 running at stock speed, the QX6850 differs typically by a few points, it is not until the QX9770 is overclocked to 4ghz that the difference becomes as high as close to 20% in come cases. However, that ignores the fact that a lot of the other processors are good overclockers, and I can overclock my QX6850, using thermoelectric chilled water cooling, to a stable 3.8. Therefore, the difference between the two in terms of speed is not enough at this point to justify purchasing an X48 chipset motherboard and a QX9770 when a new socket and extreme CPU is coming out soon. If I was putting together a computer now I would likely go cheap and look for a used QX6800 and as good a used motherboard as possible just because I would be selling them soon anyway.
