    Will I notice enough difference to warrant the price difference between these two processors?

    Nope.

    The general public is more likely to be limited by RAM rather than processor these days (number of cores notwithstanding, that is).

    Thanks. Can't see a justification in £160 to bump the RAM either. Currently running a mid 2010 with 8GB and SSD. It ain't that bad.

    My 2010 with 8gb and sdd is still going strong for my brother but I do love my 2.6 8gb 512Gb rMBP now the screen is fantastic and it is a great little machine

    Depends on your usage.
    With screens getting more high res I noticed the biggest strain on the gpu.
    Of course more RAM never hurts, except your wallet :(

    Another difference than CPU frequencies between the two i5 configurations is the i5-4308U is supposed to be able to run its GPU from 200MHz up to 1.2GHz, compared to the i5-4278U only up to 1.1GHz.
    Now, I don't think the difference would be so sensible, and I don't know how Apple can itself limit this for thermal/power reasons.

    The general public will never be limitedly ram ;) . Even 8 gigs is overkill for most people. Hard drive space is the best investment IMO since that has a tangible benefit, as opposed to the "what if in 3 years apps start requiring more ram" logic that so many people seem to follow.

    If you have to ask, the most likely answer is no.

    Unless all you do is peg your CPU at 100% load, 100% of the time, the difference is not noticeable at all.

    Put the money into the SSD, the 512 is significantly faster than the 256. I have a new 2.8 Retina with 512 SSD and it`s noticeably faster than my 2012 1st generation Retina, unless software calls for all the CPU Core`s thanks to the SSD R/W being half as fast again.

    In day to day usage you won't notice a difference.

    If you do a lot of transcoding and exporting then yes, you will notice a difference (depending on the file size).

    Get the most RAM and largest drive you can, CPU difference is not worth the extra. OS needs 7GB of RAM to load without using virtual memory/swap.
