To choose a compatible graphics card it is helpful to know some details. GPU: AMD[5,6,7,8,9]000Controller.kext (one for each AMD Radeon GPU. EFI-Init: On a genuine Mac, the graphic card carries a EFI ROM right next to. HD 7970 / R9 280X, Yes, 10.8.3, 0x6798, 2x mDP, HDMI, DVI, Hamachi, none.
Current batch of R9 280x (Tahiti XT2) is rebagded 7970 GHz edition, so it wasn't a big surprise that it works in OS X and it's flashable as well. AMD didn't even give it new device ID. It's reserved for upcoming Tahiti XTL, I think. So, new name, same chip and specs as its predecessor but much better pricing, at least. Mine is OC edition with factory clocks 1100/6000 - like 7970 GHz edition. And its performance is almost identical.
Currently both are fastest single GPU AMD cards, until 290 and 290x will come to the market. Some benchies below. If you want to see how your card is performing against this one, you should use my settings in Heaven and Valley.
In Mavericks it kicks butt in OpenCL (last screenshot), ofc in D700 clothes Edit: added Furmark scores. I really appreciate that. I had to give it name manually in EFI, drivers recognize it OOTB as 7xxx before flashing. I bought OC edition, reference clock is 1000 IIRC, where 7970 GHz ed. Mine has 1100. Actually I was a bit disappointed with performance, I hoped for slightly better bump.
My (heavily) OC'ed 7950 is almost on par with this particular 280x, at least in OpenGL. But for that price (about $100 less than 7970 GHz) it's still very good. My main concern was real power usage under heavy load. IStat, which I use now, reads max 8A on PCIe Booster. In Furmark with 7950 it shows 7.99A from both boosters and 4A from the slot. I'm waiting for Hardware Monitor license, it seems to be a better tool. I really appreciate that.

PCI-E Slot: 45W Boost A: 90W Boost B: 55W. 200W for a overclocked 7950 with Furmark is reasonable and if I swap the boost wires then the values swap. Without getting an actual Ammeter in there I could not determine if the values are correct or not!
Yeah, it's funny, but seems 100Watts on a single cable works That being said, I have twice in last 24 hours had a Titan take my 4,1 DOWN Oddly enough it was the same app that was aproblem years back with a 4870x2.good old Crysis. (Warhead version) I wanted to see it on 4K display at 60 HZ. Saw a few minutes, then I jump and when I hit the ground.click.nothing. And it isn't just a bad Titan, two different cards, same thing. So there is an app that can make Titan go past power limits. I wuld be frightened to see what that number is as I have seen steady 130-140 readings in Hardware Monitor with no crashes. And that also means that 780Ti is MOST DEFINITELY external only.
And to avoid being a complete thread jacking a-hole, Blacksheep I have seen you state elsewhere that R9 290x doesn't work yet in OSX. Does that mean you tried?
