    I know it hasn't been released, but i had seen benchmarks and news about it, how does the i7 2920 compare to the previous generation and does it have unlocked multipliers?

    Considering that i7 2630qm is close and sometime over the 920, u can imagine the 2920 .. :)

    I'm hoping that the 2920 will 'destroy' the i7 920, and I hold high hopes for it too come close to achieving.

    The i7-2920XM does have an unlocked multiplier, as does the i7-920XM (I assume that's the one you mean, and not the desktop i7-920). It has a base clock of about .5 GHz over the i7-920XM, and much better/more aggressive turbo-boost on 4 and 3 cores. So, at stock, the i7-2920XM looks to be somewhere around 35-40% better than the i7-920XM when both running flat out as fast as possible on a single core, and even better when comparing multiple cores. A lot of exactly how much better will be dependent on the cooling abilities of the notebook; a lot of the older generation had substantially beefed up cooling systems to deal with the heat of Clarksfield. With the lower (overall) temperatures of Sandy Bridge, manufacturers may be tempted to skimp a bit on the cooling, which would limit Sandy Bridge's advantages over Clarksfield. As for overclocked, well, we'll just have to wait and see. i7-920XMs and i7-940XMs have been overclocked to 3.5-4 GHz on all 4 cores, which is about how high Sandy Bridge can go with stock Turboboost (3.4 GHz). We'll just have to see how much beyond that it can be pushed.

    Oh, and not to discount the above-linked guide, but it seems to be more directed to desktop overclocking and not mobile overclocking, which tends to be rather different because we almost never have the options that a desktop motherboard allows.

    indeed it is directed to desktops, but the thing is that oc'ing SB is different than what we are used to.

    and the people of throttlestop are working in SB program to facilitate things. If they are going to succeed we can only hope so.

    SB is going to give you a whack more battery life.
