So I bought the base 5k 3.4 iMac last weekend for $1,550 but this week I saw the 3.8 version is on sale for $2,099 at Best Buy. I use my iMac for raw photography editing and recently got into some basic video editing with my new drone using premier. I’d also like to compile a bunch of my 4K iPhone family videos using the program at some point. I noticed out of the box I’m getting memory errors for during RAW photo processing so I have an additional 16GB chip on order due to arrive today. While I’m still within my return period, is it worth considering the $549 upgrade to the 3.8 with the 580 GPU? Or should my current setup be fine for my needs long term? I have little interest in gaming.
