    Thanks for these info Aaron.
    Can anyone answer my the two other questions I posted ?
    - With the i7 3820qm what is the best : 16gb of 1600MHz ram or 16gb of 1866MHz ? I'm assuming the 1866Mhz are better but i want to be sure...
    - is there a possibility to do an hardware calibration with the m6700 ips screen ?

    The screen is amazing. The E2E lid concept is crap, but that's my humble opinion after owning M17XR1/R2, M18xR1, M6500 - all E2E. I also ripped the E2E glass apart from my M18x and have the first hand experience of with vs without. In addition, I owned 2 notebooks with 10-bit IPS RGB LED matte and can say that there isn't a huge difference in image crispness after putting the laptops side by side. But there is a huge difference in reflections. The E2E glass makes the screen 10x more reflective than typical glossy panels, you can easily shave your beard indoors, hehe.

    If yo don't have skills - find someone who does. ;)

    1866Mhz ram is better, but not much.

    Yes you can calibrate the screen with something like a spyder 3/4

    The Spyder 3 can't quite measure the full gamut of the IPS screen. The Spyder 4 appears to be able to. Either one can calibrate the screen, but the Spyder 4 will do a slightly better job. The Spyder 3 is still very good, but the Spyder 4 can "see" all of the colors the screen can do.

    I too was curious about this and decided to check into it. Thus far, my research has yielded less that stellar results:

    Specific benchmarks showed the faster ram did score higher. However when those differences was averaged overall and under real world conditions, the performance boost was negligible.

    In one test results I found the WI processor score was improved by 1 point. If that amount of increase matters to you, then get the 1866Mhz RAM.

    I've concluded that like other single incremental RAM jumps there is a measurable increase in speed, but only a minor one. To me that difference is insignificant since it is unlike to be noticed.

    Thanks for the ssd benches, Bro! Looks like the mSata ssd performs exactly as it should - at Sata 2 speeds. There should be very little difference in real life performance when compared to a sata3 ssd.

    I am thinking and seeing the same thing. Unless you are constantly moving large files around, you won't see a huge difference.

    Pay attention to the IO OPS the most. The mSata and 2.5" SSD are closer than I expected. The Western Digital Scorpio Black 750gb is left so far behind by the SSD drives.

    Will ghost the mSata to the SSD and try to get some real life numbers. Things like boot times and batch processing of files.

    Is that a PM800 or PM830 ? The latter is significantly faster, even constrained to a SATAII interface.

    It looks as the IPS display is not available as an option for the M4700 on the Dell US site anymore.
