Hello, this week I bought my first Mac I am a photojournalist and I will use it exclusively for my work, although occasionally video amount to more or less professional issues (HD videos with Canon 5D and 7D). I have clear I want a Imac and in particular the high of 27 model. " So, I have the following question: Given that the Ram, Crucial buy it at a later date ... And 1GB Graphics "guess" that go well for video. Expand What? i7 3.4 or 1TB + 256GB SSD? None of the 2 things I'm going to be able to expand in the future (the processor can not, and I will not ever open the Mac but is to expand the Ram). I'm almost decided by the SSD, but I would like to know your opinion. Is it worth over i5 3.1 to i7 3.4 for 200 € more? 3.1 With the i5 I left? Regards, and thanks in advance.
