Anyone ever get AMD 7990 running?

[artherd]

In a 09-12 Mac Pro? Presumably with a dedicated GPU powers supply?

Mac EFI firmware? (boot screens)

5.0GT/sec as opposed to 2.5?

I didn't find anything about the 7990 specifically.

Anyone? Do I need to buy one and blindly try it?

That thread is from the 10.8.5 days (which should support tahiti GPUs...) We're at 10.9.4 now.

The card is not even detected under both OSX and Windows.
