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.

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.

The devs of Luxmark working on new Luxmark 3.0 - is in eary stage and not comperable with LM 2.0 results (new written renderer, new scenes!)
You can try: http://www.luxrender...pha1_OSX_64.zip
For me with 1GB VRAM, only the small scene (ball) works - others give gpu memory error.
( RUNTIME ERROR: The InfiniteLight distributions buffer is too big for GeForce GT 440 Intersect device (i.e. CL_DEVICE_MAX_MEM_ALLOC_SIZE=268353536): try to reduce related parameters)
Would be interesting if its an bug or other GPUs with >= 2 GB or 3 GB VRAM can handle the two other scenes.
LM 3.0 A1 : GT 440 1 GB (GPU Only)

Both others CPU only (due GPU 1GB VRAM to less= error message running GPU only)

Thanks! Hope we will see some with 2GB+ VRAM running the two more complex scenes
WIth 1GB VRAM only Luxball scene works (or you use CPU only)

4GB VRAM here. No memory error but with the other two scenes the kernels fail to compile on the GPU. They compile fine (and in a much shorter time) on the CPU.
