    Before I click the buy button are there any known problems with the
    ASUS P7P55D PRO LGA 1156?

    Before you buy, you could read this article on Foxconn sockets.
    This applies to people planning significant overclocks. It doesn't
    help when all the power contacts aren't touching.

    Then review the usual sources of info.

    OK, thanks for the info. Am reading it all now. I did read one review
    on the Asus P7P55D Pro and they gave it good marks.

    I usually OC but not by a massive amount, was going to put in an i7860
    but considering I already have a [email protected] I'm not so sure if i7860
    it is a worthwhile upgrade even. I know it is faster clock for clock
    but am not sure by how much.

    It runs at 2.8GHz, and has Turbo Boost.

    "Maximum Intel Turbo Boost Technology frequency per core -
    4 core: 2.93 GHz, 3 core: 2.93 GHz, 2 core: 3.33 GHz; 1 core: 3.46 GHz"

    So if you were running SuperPI single core benchmark, and Turbo Boost was
    enabled, then that single core on the processor could run at 3.46Ghz (as
    long as the other three were idle). And that would still be considered to
    be "stock" in a sense.

    These are some SuperPI 32M results for i7-860. But none of them are
    running stock.

    This one claims i7-860 operation at 4410MHz and a SuperPI 32M time of
    8 min 40 sec 950ms on air cooling.

    For comparison, I can try an E8600 C2D at 4400MHz. Completion time
    is 12 minutes 36 seconds 927ms.

    You can convert those two results to seconds and take the ratio,
    to determine the clock for clock.

    You can have a look around the site, for more results.

    SuperPI 32M allocates 256MB of system memory, while it is working.
    So that is bigger than the cache in either of those processors. It
    means the benchmark fetches from memory while it is running, and
    the memory subsystem makes some of the difference. SuperPI is a
    single core benchmark, so doesn't measure how well the thing
    works on multithreaded tasks. But I like it, as a means of
    comparing processors from multiple generations.

    You can get a copy of SuperPI here.
