I'm considering high to purchase the iMAC 27-inch 3.1 Ghz i5 and if my question are well answered, with god grace, I will confirm my order on the launch of LION OS.

 

 

The iMac will serve the purpose as mentioned below

1. I'll be working on with Pro Logic Music Full Edition (for the purpose of composing and arrangement musics)

2. Aperture 3

3. Final Cut Express

 

So basically I'll be working on publications, some video and music composing and editing. So thats my main purpose.

 

However, I'm having consideration to upgrade

 

1. Is it worth it to upgrade form i5 to i7 processor? Obviously there will be increase in speed. But my question is, doest it really shows a significant speed from upgrading from i5 to i7? Can I see the processiong speed increase alotz? and if it increase, is it just little or huge difference?

 

2. The pre installed is 4GB, by increasing it to 8GB, will I see any significant differences, especially when working out on logic express and final cut, as i believe it needs alot of memory usage. However, does the 3 applicaiton, supports upto 8GB or what? Does it really contribute to significant of increased performance?

 

3. Upon purchasing my iMac, I woud like to attach another 2 units of Samsung 27 inch FULL HD supports upto 1920 x 1080 screen resolution. So basically, there will be 2 separate monitors + 1 iMac. So is it necessary for me to upgrade to the 2GB Graphics Card?? Or just leave it as 1GB. By splitting the monitors, do I really need higher resource of graphic card? i'm NOT going to play GAME. I've heard some issues, whereby when they split the monitors, there appear to be some black coverage area, and the screen size is not maximise.

 

4. I currenlty own a External Sound Card Powered by the FireWire 400mbps, the iMac mentioned it supports up to 800mbps, so can my external sound card support the iMac. ( This is for recording and output purpose) as I won't be using the iMac speakers, instead attaching a huge Powered Speakers to my External sound card.

 

5. Finally, I'm interested in purchasing the Thunderbolt Peragus Drive which can support up to 4 to 6 terabytes. So the problem and issue now is, iMac provides

1 Fire Wire - (which I will be using for External Sound Card)

Thunderbolt - 2 units, which I will be using it for 2 monitors

Peragus Thunderbolt Drive - I HAVE LACK OF ONE THUNDERBOLT CONNECTION. SO HOW?

 

can I use the 1 unit of thunderbolt to output into 2 EXTRA MONITORS?? My monitor supports HDMI, and DVI signals. And If yes, Will there be a PIXEL DISTORTION or BREAK?? I mean I really want a clear view of the monitor, without any loss of quality. So please suggest me. I'm extremely new to MAC, and I need very good professional advice.

 

I would be thankful, if you guyz could answer me clearly, according to the question.

    I think no one has answered this long post because... it’s rather long!  And no one may have all the answers that you’ll find satisfactory.  But I’m young and foolish so here’s my comments:

     

    Yes, if you can afford it, go with the i7 processor option over the i5.  It appears Apple is only supporting hyper-threading on the i7 processor so not only will you have a faster processor in terms of GHz, you’ll have a faster Turbo Boost and hyper-threading which means you could double your processor performance.

     

    4 GB of memory for things you want to do will not run as quickly as it would if you installed another 8 GB of memory.  Just leave the original 4 GB memory alone in the slots and add two 4 GB memory sticks in the empty slots.

     

    You should not need the 2 GB memory card if you are not playing games,  The 1 GB card should be fine.

     

    You need a Firewire 800 to Firewire 400 cable and you should be fine although if you have the option, you might just want to plug Toslink optical cable into your sound system directly.  You know best if the external sound card has additional functions you need.

     

    The iMac 27” 2011 machines have two Thunderbolt port.  To each port you can connect up to six daisy-chained devices with the connection to the monitors being the end of the chain.  So no problem, you can have three high definition displays if that’s what you want as well as other devices like the Thunderbolt external disk drives in the chain.

    I'm a bit confuse.

     

    1. You mentioned to install another 8GB. Are you trying to say the total memory will be 12GB??

     

    How's the situation. Is it like this

    1st Slot - 2GB

    2nd Slot - 2GB

    3rd Slot - 4GB

    4th Slot - 4GB

     

    When you sum up, you get total of 12GB, which I don't think so can be configured in apple store. The options are 4GB in each slot, when you plan to upgrade from 4GB to 8GB or 16GB only.

     

    2. You mentioned that I don't need 2GB memory card, however, my question is, by splitting the monitors into another 2 additional monitors, will the graphic display will be compromised or not? To be more clear, will I have an accurate display or a bit less quality display?

     

    Finally, Thank you so much for your reply. I know, its pretty long and you gotta take time to answer it.

    I use Logic Pro running multiple samples (VSL Symphony & Choirs)  from external HD connected by FireWire800. I recommend getting as much RAM as the machine can support because you will have fewer issues with samples, multiple tracks using many effects and plug-ins. My best advice: the fastest CPU, the most RAM that you can afford at the time of purchase. RAM is an easy after-market upgrade but not so the CPU. Best to get the highest  specs right at the start to avoid disappointments on your early projects.

    Yes if the way the slots are numbered result in matched pairs of memory, i.e. nothing to worry about if the Apple-supplied memory is not touched as they’ll be a matched pair; just add the two 4 GB sticks in the two empty slots. 

     

    If you don’t install the memory in matched pairs, it will work but you won’t have dual path access to the memory so the memory will be slower.

     

     

    When you sum up, you get total of 12GB, which I don't think so can be configured in apple store. The options are 4GB in each slot, when you plan to upgrade from 4GB to 8GB or 16GB only.

     

    Yes, the total would be 12 GB and you buy the additional 2x4GB memory sticks from either Apple at the time you purchase the computer or from a third-party vendor - but you must be careful to get the correct type of memory.  Sites like OWC can be very helpful guiding you.  If you buy from Apple, you cannot add to the device via the configuration options as you pointed out.  But once you initiate the online purchase, you’ll be able to Continue Shopping for other items such as memory to Add to Cart before you Checkout.  It’s easy to install memory yourself.  Just be careful to buy the memory exactly designed for your machine!  Any tiny variance and the memory won’t work; it’s not too difficult but read the specifications carefully.

     

     

    2. You mentioned that I don't need 2GB memory card, however, my question is, by splitting the monitors into another 2 additional monitors, will the graphic display will be compromised or not? To be more clear, will I have an accurate display or a bit less quality display?

     

    I am sure that graphics card with 1 GB will support the three displays if you are not using the computer for gaming.  If you are gaming, then you might want the 2 GB card.  You can prudently call Apple to discuss if you like.

    Hello Rick Lang,

     

    WELL ANSWERED!!

    Thank you so much for your reply!!. I shal now proceed to find out how much memory can the Logic Pro Software supports.

  • Kalimullah Khan Level 1 Level 1 (0 points)

    Hello KENNETH

     

    Can I know what is your iMac configuration? and what sound card are you using? U mentioned that you are using Firewire 800, so are u using an USB Sound Card?? Please Clarify

  • kennethfromtoronto Level 4 Level 4 (1,035 points)

    All the hardware I use is standard Mac hardware that came as the original configuration from Apple. I do not use an external sound card. Here are two screen shots showing my hardware & graphics which I use to run Logic Pro 9 quite successfully:

    iMac-graphic.jpg

    The Vienna Symphonic Library  samples are stored on two different external drives both having FireWire800 ports, daisy-chained together and connected to the iMac using a FireWire800 cable. I hope that this clears up some of your questions. If you have more don't hesitate to respond.

    Hello Rick Lang,

     

    Sorry to bother you again. Well I did went through the owc website. It was extremely helpful to me. Thanks to you.

     

    I found out that I could purchase RAM from the OWC at a very cheap rate. For instance, If i buy the 16gb (4GB x 4) it cost USD 210 approx and with shipping I can still manage to save 50% of the cost.

     

    Well, what RAM does APPLE actually uses, and what RAM do u recommend me to buy? Perhaps I can just go for basic RAM which is provide by the APPLE (2GB x 2) and get the OWC RAM of 16GB, and take uot the 4GB ram which is provided by the Apple. What is your concern and opinion??

  • Kalimullah Khan Level 1 Level 1 (0 points)

    Hello Kenneth,

    Thank you for your reply. Well, I've included another on the below post. Kindly go through it and reply me if you can. And another one more, can I know how much RAM does Logic Pro supports? Have you experienced any HANG or CRASH while using the Software? I'm a PC BASE User and I've been using Cakewalk Pro for a long time. But sometimes, if i'm using it quite long, the computer crashes and gives some issues especially the BLUE SCREEN of windows.

     

    Thats the reason i'm shifting to iMAC

    If you are on the OWC site, they describe the models of Apple computers supported by a given memory stick.  Just be sure it says something like “compatible with iMac (2011)" if you buying the latest iMac model.  It needs to be 204 pin, non-ECC, etc. but OWC knows all this and you just need to verify the memory stick is compatible with your iMac model by year.

     

    If you want to use the full 16 GB, that’s fine.  OWC will even give you some trade-in allowance for the 2x2GB sticks that Apple supplies but check their site to see if you need to return the Apple memory at the time you buy the OWC memory - sorry I’m not overly familiar with the details. 

    In the rare event you might have a memory problem or some other weird things happening on the iMac in the future, to me it’s worth keeping the original Apple memory sticks.  If you have a future problem, Apple may ask you to reinstall your original Apple memory before they’ll agree that the third-party memory is not the cause of the future problem.

     

    I bought 16 GB from Apple for added peace of mind, so that’s why I don’t know all the details, but for a small risk, you certainly can save money buying elsewhere.

    It is the logic board that supports the RAM. A pro application like Logic needs quite a bit of that because the samples alone often require an enormous amount dedicated just to run one sample. An example from my workflow, setting up a project for a full-size symphony orchestra with choir, requires that Logic have access to the following amounts of RAM. In order to serve one Flute track the part requires only 7MB; one track of Double Bass needs 5MB. But when I call for choral tracks here are the requirements: one track representing a section of 16 Sopranos = 23MB; one track for 10 Altos = 24MB; one track for 10 Tenors = 23MB; one track for 8 Basses = 27MB. For the orchestral parts there are Flutes 1&2; Oboe 1&2; Bassoon 1&2; Clarinet 1&2 + Bass Clarinet; and so on throughout the brass section and percussion section. This is required just to access the samples. Your computer has many other tasks to run at the same time. You shouldn't have your browser running nor should you run your email editor, but the system still needs to run and requires resources. You will have to drive multiple displays ( I use an external 20" Cinema Display in addition to the iMac screen). You will be adding effects on the fly and tweaking EQ, Compressor, Limiter settings and so on; this can all be done with no stuttering  with an i7 Quad-Core since you have 4 cores + 4 virtual cores. I have not encountered problems on my iMac with the hardware configuration that I posted above. I can understand your hesitation about such a big change from Cakewalk on Windows; I think that you will find a large measure of satisfaction in reliable performance from the iMac that you are considering to purchase.
