    I have a mid-2012 2.6GHz quad i7 Retina MBP (then top of the line). Now I'm looking to upgrade, and since I got an MBA now it rarely goes outdoors - it's more like a stowable desktop now. I'm considering eitber the current top line MBP (2.3GHz quad i7 I think?) And the current top line 21" iMac (2.9GHz quad i5?) Question is - will I suffer a processor performance hit on either buy? The rMBP has a clock speed hit, the iMac has a class hit to i5. I actually want an i7 iMac, but they're not available in my country.

    The heaviest thing I do is really just the occasional StarCraft 2 or F1 2013. Other than that it's iWork or web browsing or some other.

    Why upgrade that nice machine if you are not using it at full?

    Even though the new rMBP (2.3) has a slower clock, it's still faster that your current one (2.6); it's about 8% on average faster than you old one (the new 2.6 is about 14% faster than your computer).

    Anyways why not buy a display instead of a new computer? That way you'll still have a powerful portable Mac should you need it.

    I really don't need so much power whenever I'm traveling, so I don't need the mobile capability. My MacBook Air does that well enough.

    I do have my reasons for upgrading - because the next person in the hand-me-down chain needs an upgrade!

    Would the i5 iMac (with BTO not being an option in my country) be a step up, or a step down from my current retina mbp? I'm looking at the iMac because if I don't need a mobile computer other than my Air I might as well, no?

    The tradeoff in my mind would be that while the iMac is cheaper, and bigger screen, I wonder if I'd miss retina, and whether I'd be taking a step back in performance (HDD rather than SSD, i5 rather than i7)

    Imac with fusion is a good performer.
    The imac has a desktop CPU, so it would be fast.
    For the screen, you would have to try it.

    Going from a SSD back to a HD can be quite a noticeable performance hit. You might want to consider upgrading it yourself to a SSD or make your own Fusion drive. As for Retina to non-Retina that is more subjective. I finally sat down and used a Retina MBP and it didn't look any different to me than a non Retina.

    Is it upgradeable? The HDD to SSD I mean. Is it upgradeable post-sale?
