I am ordering a new imac,replacing 5 year old iMac and have a question on which processors to order. My question is i5 or i7? I am an average user whose usage is variable. What I mean by average and variable is, I am not doing heavy graphics or gaming. I use business applications , some personal photo editing and an occasional game. I know that either processor will be significantly faster than my current one. My thoughts are an i5 with fusion drive and 16gigs of ram given that I am not what I consider a power user. I am looking at another 5 years of trouble free use on the new machine with ability to update OS and applications as needed. So is the i5 a sound choice? Pricing is not a deal breaker, however I do not see a need for overkill. Side note..I have read the i7 runs much hotter than the i5? Thank you for your time and feedback.
