    I'm thinking of buying a 920XM to replace my 820QM, but I'm not sure if the difference is big enough. I've heard that the 920XM can be OCed and tweaked to near desktop performance, is this true and stable? Is the difference that great?

    10 W more power outage and probably more than 10 W required extra to run that CPU. Why not get a 940XM so you get more than a negligible upgrade?

    Also why would you need such a CPU? Games will see basically no change, video encoding will see some change, and really I can't think of anything else that will see an improvement. Unless all you do is benchmark.

    Oh and you'll probably need like a 150 W adapter.

    Yeah, the highest end notebook CPU can match a low-medium end desktop CPU... depends on the cost and your usage, as stated above, the difference wouldn't be much.

    In AW and probably Clevo systems - yes.
    As for the M15X - what's your max gaming 820QM temps?
    Also, did you replace the paste on it already?
    If you can keep your current CPU under 80C in Prime95 - go for the extreme.

    Id go for the 940xm the difference is small between the 820 and 920. I actually am planning to goto a 940xm or 840QM now that Alienware released the BIOS support

    is it true that the 920xm turbo boosts on all 4 cores at the same time? i've seen some people say that but if it's true it doesn't look like it's that widely known. if true, it would be a huge upgrade from the 820 on video encoding, photoshop, etc.

    Every Core i w/ Turbo Boost can boost up all 4 cores at the same time, hence balancing out. Unless the Extreme one can boost up more, which I sincerely doubt.
