I second eep357's post as last time I recalled the Lightning edition of the 580 looks something like:

Unless you took a Lightning cable as shown:

and plugged it into your Lightning 580 card to OC it a good bit. My assumption could be incorrect it's just a theory.

Card is clocked at 940 Mhz GPU thats why it says 1880 Mhz ,thats the shader speed,double GPU speed.
My point is that scores in Luxmark can be falsified with modifying the benchmark itself,maybe the new 10.8.3 update somehow does this unwillingly. Thats why eep got a huge jump in score.On the other hand those ATI cards are monsters in OpenCL.

Well, you were partially right. I didn't modify the benchmark, but it appears as though when I reset my BIOS to stock yesterday while having my prior overclock values in Clover's config.plist it caused a mismatch between internal core clock and what OSX what expecting, results=inflated benchmark scores for CPU & GPU, with no real world performance gains (actually everything running slower, even video which gives a FPS boost cause seconds last longer allowing more frames, but it can be hard to see difference) :( Since I have no interest in cheating benchmarks, I would have to say all those benches from yesterday are invalid. 7970 still kills it without cheating :)

Managed to squeeze 1250 MHz from my 7950 and it kicks butt in Luxmark. Pretty close to R9 280x I owned before. Did it only for benches, normally it runs @1175 MHz – balanced performance/heat/loudness setting.

So far 10.10 is a step backwards performance-wise.. lost ~170 pts in Sala with DP2, compared to Mavericks. But the jury is still out
