    About a 180$ upgrade, and the only thing you get is 2mb of L3 cache. Does it really make a difference for gaming or only benching?

    Don't do it. 100Mhz faster and 33% more ram is not worth $10 let alone $180.

    for gaming it makes no difference. Your GPU will bottleneck before the CPU. You don't even need to get the 2720QM (unless you need the VT-d support), the 2630QM is more than sufficient for gaming.

    RAM and cache are not the same thing. Same reason RAM and HDD are not the same.

    No, it's not worth it. Pretty much the only quad core that's impossible to justify.

    Thought so. But I'll keep the 2720QM over the 2630QM as a prime choice because of the IMC speeds for the ram (want to get 1866 kingston sticks). Everything else is identical to the 2820QM except the cache. And I like to fold...


    Other Question: Many laptop resellers offer 4 sticks of ram now in the laptops, but aren't the IMC voltages on the CPU still limited and perform better when OC's are done with only two sticks? Or are Lappies different from desktops?

    It's not worth $100 jus for slightly faster memory. You'll never notice the difference.

    although i have gone with this upgrade, i think there is only a very marginal benefit from 2720QM.

    the money that is saved is perhaps better spent on memory.

    The 2820qm is not worth it.
    The RAM speed difference you will never notice, and in terms of actual CPU differences... they are marginal at best (you might only notice it in programs such as 3d Studio Max, and even then you would gain a few extra seconds over the 2720qm).

    Stick with the 2720qm.

    Save that $180 and spend it for a decent SSD. It will be a much more useful upgrade.

    It's not worth the price at all. So little gain.
