no i wouldn't upgrade...i don't do MU either cause i am sports med and all...but honestly the annoyance of a couple things sucks! 1. if you send stuff for your doc to sign off on, when he/she signs it, it no longer deletes from his/her box...then you have to at the end of the day manually hit delete multiple and clear them out...
2. slow as hell
It depends on the setup of your server/computers/memory/processor speed... etc. I am running AC 7.1.3 in 2 settings. One as a backup with a server running WIN2008R2 and the other in LINUX PROXMOX as a virtual machine using the same WIN2008R2. I have had no problems with slowing down at all.
