    So, in looking at the non-retina 13" MBP, what am I getting if I opt for dual core i7 (+$135) over dual core i5? Is there really that much difference for movie rendering, etc.?

    Turbo boost, cache size, hyper-threading.

    If you encode a lot the i7 should be a bit faster, but a quad-core will run circles around it.

    The i7 has 4mb cache. The i5 has 3mb cache.

    That could theoratically bring you a 20 - 25% speed increase.
    The speed increase in reality will be ~8%.

    Between the dual core i5 and dual core i7, the only difference is the clock speed.

    Thanks, if I decide to move ahead, I think I will opt for the i7, since, in the non-retina MBP, it is the only thing I can't update later.

    I would consider a refurb 15" but I currently have a late 2008 15" and am thinking I might like something a little smaller/lighter; plus any 2014 MBP would run rings around my 2008......

    The cache doesn't really make a huge difference except in benchmarks.
