    I have been waiting to upgrade my 2005 iMac and wanted to see what the new rMBP had to offer.

    I will be buying the loaded option 1tb 16 gig RAM etc or the 768k 16 gig RAM ivy bridge.

    Trying to decide whether the Haswell is worth the extra $500 or so $$

    The refurb store has this:

    Refurbished 15.4-inch MacBook Pro 2.7GHz Quad-core Intel i7 with Retina Display
    Originally released June 2012
    15.4-inch (diagonal) Retina display; 2880-by-1800 resolution at 220 pixels per inch
    16GB of 1600MHz DDR3L SDRAM
    768GB Flash Storage
    720p FaceTime HD Camera
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory

    for $2399 which is a decent saving over a similarly equipped Haswell.

    Obviously I lose 256gig of storage and faster wifi and graphic and processor, but for what I do it will most likely be plenty fast enough still.

    I want to future proof as much as I can as I will hold onto this computer for a long time, so the lack of TB2 could be an issue, except I am not familiar with limitations so any input is appreciated.

    TB2 offers increased bandwidth so that you can run (future) 4K/retina displays.

    hmm that is a bummer, I remember reading somewhere that people had been driving 4k with the ivy bridge. Is that not the case?

    Looking at the available 4k displays:

    It looks like most do it via 2 cables.

    And from


    It looks like you can technically do it on the 2012, but of course you'll be using 2 thunderbolt ports to push pixels, whereas you could *technically* use one TB2 port on the new rMBP.

    I don't have any direct experience hooking up these displays to either machine though, so take my information with a grain of salt!

    Interesting insight. I'm probably not going to worry too much about TB2 then since the original TB is still very expensive.
