Hi Adobe family!
I run a late 2014 5k iMac. Its 4.0 ghz, 32gb RAM, 1tb fusion(unfortunately, I know).
I'm having a lot of trouble in lightroom. My sunset skies get stuck being pixelated sometimes for minutes. I don't remember this being a problem in the past. I also recently got a 42mp camera, and the files lag a bit. I was considering getting a new 2017 iMac, but Im not sure if its worth spending 3k to get up to a 4gb graphics card. I'm assuming thats the big issue, not the fusion drive. My photos are stored on a thunderbolt RAID drive with speeds of a little over 300mb/s each way. With high sierra coming out with support for egpu's, I'm wondering if thats a better answer. I do only have thunderbolt for connectivity though, not thunderbolt 3 that the egpu's that apple is selling require.
I'd much rather spend $500 on an egpu, when everything else my computer does works fine. Can you guys tell me if
A) It sounds like the graphics card is my issue?
B) Have any recommendations of a graphics card that will work with High Sierra, needing a thunderbolt 1 connection?
As always, thanks folks!
