My recommendation: 1. Keep the current build, at least until Apple FINALLY announces something new, hopefully this fall. Add more RAM, basically max it out, I believe it goes up to 128gb. Next get an external gpu enclosure, razer core x is probably the newest/lowest price... need to check thunderbolt gen compatibility there, but I think it should support whatever the Mac Pro can output. If not there are plenty of options here, and I think bizon tech has chat support. In this you can add that 1080 or, if a little better would be one of the newer Titans (you can get an enclosure with card included on bizon's website). Some folks mentioned the separate drives for cache and your work files and I can confirm that it makes a difference. OWC has everything you might otherwise need to upgrade internal storage or ram. Thunderbolt ssd solutions can be used to add fast drives without opening the hood. Happy rendering. PS. If you really want to the ultimate machine, I would suggest getting a PC build with either 16 core Ryzen Threadripper or 18 core Intel i9, 128gb of RAM, multiple m.2 ssd drives (for splitting up os, files, cache), and a Titan V GPU (just released). For archiving and regular backups of your production files, Seagate is making 12TB baracuda pro drives now, and I would mirror a few of those for safety. Then, back all that up to an NAS in another building, at least 32TB to hold you over for a lonnnng time.This is what I would do if I was given the company card and asked to get the best (not the cheapest). Whichever way you go, good luck and happy rendering! (Someone please check my facts here and make sure I am not off base about any of this... I'm a creative professional and these are my opinions based on what I currently understand about the tech.) Cheers, J
