iMac Performance - will I be happy with this new iMac?

    Hi all,
    Its new Mac time.:D
    Oh the smell of Apple packaging as I open for the box and for a moment forget their dodgy tax avoidance. Joy!

    Its a while since I bought a new Mac.
    I'm currently using a 2009 MacBook Pro
    2.5 Ghz
    Intel Core 2 Duo
    4Gb RAM

    It does the job, though I regularly get "System Overload" messages when I include the kitchen sink in my arrangements.
    (EZ-Drummer and Focusrite compressors are my two 3rd party workhorse plug-ins and I sue them at will).

    I'm likely to get a 27" iMac.
    3.2GHz quad-core Intel Core i5
    Turbo Boost up to 3.6GHz
    8GB (two 4GB) memory
    1TB hard drive1
    NVIDIA GeForce GT 755M with 1GB video memory

    Am I likely to see a nice jump in performance?
    Anything I need to watch out for?

    Thanks all.

    I would get an i7.

    Thanks guys.
    The i5 knocks spots of my current machine according to benchmarks.

    Yep, the i7 would be great but could stretch the budget too far.

    CSeye - is there a place to find out which models are RAM upgradable?

    I understand but over a 4-5 year period, which is generally how long you get without having to upgrade, it doesn't amount to much a year. I would still encourage you to save up a little longer if you have to to get the i7.

    Okaaaay -
    How about a refurbished:

    Apple iMac 27" 3.4Ghz i7 1000GB HDD 16GB AMD Radeon HG 6970M 2GB GDDR

    Bump the RAM up to 32 GB and you are sailing smoothly IMHO.

    Thank you Jay.
    As you can tell its been a while since I've bought a new music machine.
    Your help is invaluable!

    You are welcome but this is just my opinion. Someone else may chime in and say that a new i5 actually benchmarks higher, but I trust i7s more.

    For info the refurbished model I'm looking at has a Sandy Bridge i7.
    Would that make a difference to thoughts ?

    You didn't mention how large your projects are and whether recording more audio vs. software instruments?

    While I agree with the recommendation for the i7 processor, decisions are always a balancing act between actual need and the state of one's budget.

    I have a 2006 Mac Pro that was kicking out 85 tracks without issues.
    My 2010 i5 MBP could handle about the same.

    Do your homework and make a decision that strikes a balance for you.

    For sure, get the i7. The i5 chokes on heavy DSP like processing used for VIs, even though it sails through other types of processing.

    I'm with Jay, get the i7. I just recently upgraded to a 27" retina display iMac bumped up to 4.0 ghtz. So far, completely smooth sailing. And, as Jay suggests, I am hoping to get a smooth and clean 4-5 years out of this machine.

    But they don't for 64 bit multi-core performance, and that's what counts for Logic.

    FPU matters too. For plugins.

    According to this:

    i7s do seem to score higher for 64 bit multi core performance than i5s. For example, an iMac (21.5-inch Late 2012) with an Intel Core i7-3770S 3100 MHz (4 cores) scores 13184 in 64 bit multi core, whereas a newer iMac (27-inch Late 2013) with faster higher clocked Intel Core i5-4670 3400 MHz (4 cores) scores 11806. Or is that a bad comparison?

    kind regards

    That's exactly the right comparison.

    And I can tell you, my mid-2011 i7 iMac with SSD system drive is blazing fast, and up to everything I through at it, 24/96 and up.

    Clearly, Asher's recommendation earlier in this thread is irrefutably the best option.

    I use a 3.4 i7, with 9 GB, no problems, running 64.
