Hi Guys I am gonna order the 27" iMac 2012. In my part of the world, I have two options which are roughly equivalent in terms of price: 1) The "lower" 27", with Fusion 1 TB 2) The "higher" 27", standard configuration The latter will obviously give me more processing power and a better graphics card, but the former will give me that sweet SSD. Which would you prefer? My use is primarily for my work, which is scientific and involves quite a lot of calculations, linear algebra and the likes. I also play games once in a while, and I am a hobby photographer with a 2 month daughter, so I take alot of pictures. I have a NAS, so storage is not an issue. I intend to purchase two 8GB sticks seperately, so will have a total of 24 GB ram. Thanks in advance for your comments.
