Just upgraded my main system to top of the line Apple iMac. Its an amazing machine and SO FAST!
4 ghz, 24 GB Ram, 512 SSD Drive, 4 GB Video Ram, 5K 27 inch monitor.
I been using Macs for years and IMO they are they best computer you can buy. However when getting a new system they are so much work to get everything ready for production work. It will be worth it but now I must get off all my content on my two other older computers. Lots of work ahead of me but it will be worth it.
You should see this screen. Amazing!
