Wow! That is all I can say about my new iMac. This thing is a screamer and by far the most powerful computer I've ever had the pleasure of owning. It just replaced my 24" iMac (8,1) C2D 3.06GHz 6GB RAM (800MHz) 1TB HDD, which isn't a bad machine at all. In fact I am just moving it to another location to continue using it. Does anyone recall those old Maxell commercials where there is a guy sitting in a chair with a scarf on and the sound/light from their "quality" product blows him away? Well that's how I felt when I first powered up this 27" iMac (11,3) and the first visual thing you get is the brilliant white screen with the OS/X startup sound. (See Maxell photo attached). I bought this as a refurb item from Apple. It came with 4GB RAM installed, Magic Mouse and wireless keyboard, Core i7 CPU (2.93GHz) 1TB HDD. The only other thing I bought was the AppleCare and 16GB (1333MHz) of RAM from OWC. The iMac w/AppleCare was $2,181.94 and shipping was next day for free. The 16GB of RAM from OWC was $233.98 for a grand total of $2,415.92. Had I bought this as new from Apple with the RAM from Apple as well I would have paid $3,368.00. So I figure I saved $952.08 by buying refurb and getting RAM from OWC. Sounds like a good deal to me. Plus the built-in speakers sound much better than the 24" iMac; it's more pleasurable to listen to. I can't wait to start rendering video with this to see how quickly it accomplishes it.
