Nice to find an post that relates exactly to one's situation, thanks.
Currently working on a 2013 27"iMac and having been watching the spinning wheel for too long now. I am trying to work primarily in 3D, VW 2019, mainly OpenGL modelling (although with a fast new iMac might render more), 300mb+ files, singe family homes. I'd like to add more to the models and have more viewports, but can't as I have to keep file size down now.
The upgrade will be amazing regardless of what configuration I go with, but has anyone had real life experience with the difference between the 580x GPU vs the Vega 48? Is the speed noticeable on VW? I've read from 30%-40% faster (https://geekynerdytechy.com/radeon-pro-580x-or-radeon-vs-vega-48/) to BorderDog's 10%-12%. The problem with tech reports is one doesn't know if that extra speed will be utilized on one's typical workflow.
Up here in Vancouver it's $585 CDN more for Vega 48 which isn't a problem on it's own, just all the upgrades add up; 8 core +$500, 1TB SSD +$375. The tempting $3,079 base balloons quickly and $4,539 is getting visually close to $5,000!! 🙂.
