Well, I may have spoke too soon. It works, for about 5 mins then I get a kernal
panic and it reboots itself... did this 3 times in a row over the course of a few minutes until it wouldn't give any video at all... thought it wasn't booting up so I put my old amd 5780 back in and yes, it's booting with that card but I don't yet know what's causing the panics... I have all 3 reports from that incident, is anyone here able to decipher such things? sooo close!

The card could be faulty. I'd recommend testing the card in another system if you can.

I plan on adding some new drives next week, partly for a windows partition, so if I can successfully boot up on this card in windows would that indicate that the card itself is ok?

If you can boot into windows & run 3dmark time spy & fire strike without any issues I'd say the card is most likely ok.

oh absolutely... I downloaded the latest webdriver 367.15.10.35f01 (and latest CUDA 8.0.63) and installed them right before I swapped out my old card for the 980 Ti.  That was this past Tuesday evening, and it worked without a problem for a couple hours, had one black screen reboot, but that was it.  It being a Kingpin edition with two 8pins and 1 6pin port, I initially had the two internal 6pin connectors in the mac hooked into a 6 to 8pin adapter and put that in one of the 8 pin ports, and let my 750psu handle the remaining 8 and 6 pin ports.  But because of that one reboot, the next day I thought I'd have the card running fully off the external psu in case lack of power was responsible.  So I reconfigured it, everything ran fine for a while but then I got 3 kernel panics just a few minutes apart (which are the logs further up) and on the 3rd blackout, it never rebooted. I reset the PRAM/NVRAM and still nothing but now I'm learning that the nvram reset may have caused it to go back to OSX drivers but I don't think so.  In any event I will check that when I get home from work but that's a thin slice of hope right there.  I was hoping someone who can read logs like this could discover the root of the problem or maybe some conflict of some kind?
 
Full disclosure I was running Mad Max at the time, and that's a pretty beefy game I'll admit but come on, a 980 Ti can handle that?  It ain't Crysis.  Also beforehand I was messing around with After Effects and enabled Metal support which I hear is pretty bad and buggy and I don't see how that would affect a video game after the fact, but the point is, I didn't get this card for games, I primarily got it for After Effects and C4D so I really need this to work :-p
