For those who don't wanna download the images. Luxmark Score is 765. Unigine Heaven score was 709 @ 28.2 FPS average.

Dell OEM Reference HD7770 2GB (got this one for free just had to reflow the board!)

Works perfectly in 10.9.2 with Chimera r2.2.1 using GraphicsEnabler=Yes with Intel HD Graphics disabled in bios. Did not have to mess around with frame buffer all resolutions work on HDMI have yet to do DSDT edit for HDMI audio

10.9.2

i7-4930K @ 4.4Ghz
R9 280X GPU Black OC edition
7970 Ghz Edition
32Gb Ram
Gigabyte X79-UP4 rev 1.1 bios F7

Luxmark is giving me scores of 2278 with 1 GPU, 4647 with both GPU's and 5048 with the CPU added. Heaven is 1935. With Heaven supposed to detect multiple GPU's I thought the test may have benefitted from this. I may swap GPU slots to see if there is any improvement in single gpu score.

GE=No, AtiConfig=Junsai

Geekbench 24571

Still looking for a solution to get the display ports fully functional.

Update. Changing the GPU's around has resulted in slightly better performance but more importantly a 6-7C temperature drop.
