I am getting ready to order the new iMac. Here's where I am struggling with a decision. The upgrade to i7 is actually reasonable. The question is whether or not the extra power is really noticeable in real life situations. I've seen a lot of discussion on the topic, but most talk about either synthetic tests or specific applications (video editing or coding). So, here's the questions. What about everyday use? Let's say a situation where you have several spreadsheets open (some with Macros) and email, calendar, a browser with a few windows. Maybe occasional Photos editing? How about working with graphics intensive presentations and sales sheets? Long reports with lots of multimedia? It seems like the i5 will handle all those tasks smoothly. Will i7 be better? If so, will the difference be noticeable? Thanks for your input.
