Did you know that a GTX 980 can drive a Dell 5K display at 5120x2880 --- just like the iMac 5K?

"With a little help from my friends," I got it to work on our 2010 Mac Pro tower:

This is actually pretty cool Rob and it is amazing the useful life span of the 2009/2010 Mac Pro machines with all the upgrade options available these days.

The new GTX 980 seems an amazing card given that the power draw is now OK for just the built-in two 6 pin connectors (which the last few generations have exceeded).

I would love to see an official Mac version (maybe from EVGA like the GTX680?) that solved the need for the web driver to get at least a display for troubleshooting etc. as I always sell my old GPUs to part fund the new one so that's pretty important.

It will be interesting to see if AMD come up with a competitor that also has low enough power to get by on the two 6 pin connectors and that can be flashed to give boot screens with the built-in OS X drivers.

I know I'd much rather have a Mac Pro tower with a 5K external display and a 980 than the 5K iMac with that craptastic GPU. Awesome. Thanks for testing this!

You should really eat a better breakfast.  Yes, the Admin Panel shows me that too, it's much like the panels the quest givers in Borderlands use.  I can see you in the bathroom.

Denying you're a god? Someone needs to rewatch Ghostbusters.

Going back to the original topic, there is a way for me to put a 980 in my 2009 mac pro?

Yes you can either use a regular PC one (no boot screen) with two 6 pin power connectors or macvidcards offer one with a Mac EFT so you get boot screens.

Either way you must be running Yosemite and have the Nvidia web drivers installed before installing the card - this is the only thing that is an issue for me as I sell my old cards to fund the new one so need the machine to a least give me basic video for troubleshooting.

Performance and power consumption wise the 980 is a fabulous card.

I've never done anything like this before, so thank you. If I can get a 980 in my Mac Pro then I can extend it's life by a few more years, which would be fantastic.
