@tonymacx86 do you have 3 video cards in your system?
I'm already using iMac12,2 ... iMessage working and I hate to screw that one up.
Can I easily just change definition to iMac14,2?
Sierra seems to prefer " integrated" graphics and display modes. A possible plus for you could be the ability to add another card in a " crossfire" type of set up. I have a pentium g3258 haswell and I was able to get my R9 270x to act as integrated and my RX 480 got acceleration.I'm on 10.10.5 with a clover install running 5.1 on an X99 board with a 5960x. Any reason I need to switch from 5.1 and I'm curious if anyone knows of any other issues I might face in an upgrade with the X99 and 5960x combo.
Since there is no mention of this in the post, am I right to assume that any hack running on Mac Pro 3,1 should function identically using iMac 14,2? It took me a while to get Clover running properly on my Z77 board so I don't want to risk breaking anything (I don't care about iMessage, just the core machine and 980Ti).

You said: Just a reminder: If you're on a Hackie with a using the MacPro3,1 sysdef, you need to change to iMac14,2 (unless you have no dedicated GPU card installed, in which case, iMac14,1 will be better).
what does the iMac 14.1 profile make it more appropriate if using a dedicated GPU card over the 14,2 definition?
Pcie slot capability?
