I saw a 2014 3.0GHz i7 with a 512 SSD on refurb a couple nights ago and ordered it. Really hoping like some refurbs it was a BTO/CTO with 16GB and it wasn't listed. They don't always list the RAM improvement and you just get it. I am a believer in RAM and am replacing a late-2013 iMac 3.2GHz Quad-Core i5 with 24 GB 1600 MHz DDR3, a 256GB SSD, and a GeForce GT 755M 1GB GPU. Why would I do this? ... Well, I mainly use our iMac for a iTunes server/iPad and iPhone content sync and then apps like iPhoto/Photos, Quicken, Safari, Mail, DEVONthink, etc. Nothing too high end. Most serious graphics draw is if I watch a movie on it (rare) or Sling because my wife has tied up the main TV. - However, I work from home more and more and need two screens. I am getting a new Dell laptop for work which I use QuickBooks Enterprise and Office primarily but need screen real estate for spreadsheets, emails, and accounting software. I use 2 24" screens at work. My plan is to hook the Mini up to a Dell / LG / or Samsung 21:9 34" Ultrawide at 3440x1440 and have that available for my Dell laptop as well. Questions: 1. I have ready the Mini can push the 3440x1440 even at 60Hz. Any issues? 2. For my uses will there be any performance issues that I will notice going from my Quad-Core iMac to the Dual Core Mini? Do I want the i7 I ordered for the screen and to make up for the downgrade? 3. Do I return the Mini if it doesn't have 16GB? I like to keep it running and when I do use it, I like to have a lot of apps and browser tabs open without managing my usage. 4. Any other issues I should consider?
