    I generally don't think they are worth the cost and opted not to get the upgrade last year. An extra $200 on a ~$3k laptop isn't too crazy, but for me it was and still would be a no. GPU's typically depreciate faster than the CPU's.

    Usually u gain 5-10% processing power. So depending on ur use case this will help for rendering or video decoding.
    But not for surfing or office ;)

    Do you mean the 2.9 GHz one Vs the 3.1 or just in general?

    If the former and its 2.9 vs 3.1 you mean then no...probably not.

    I am not super educated on this, but there may be a bigger difference going from 2.8 to 2.9 because there is a jump from 6MB L3 cache to an 8MB L3 cache with that upgrade. 2.8 (7700HQ) to 2.9 (7820HQ) is not simply a clock-speed upgrade. Going to the 3.1 (7920HQ) is a clock-speed only boost I believe, so probably not as valuable.

    The 2.9 will be faster by 0.1GHz

    Plus an upgrade from 6MB to 8MB L3 cache, which can be beneficial in some workloads.

    I am also thinking about the bigger cache benefit. I wonder if 2.9 (7820HQ) will sap more energy and release more heat than 2.8 (7700HQ)?
