[Bf-cycles] Collecting official benchmark results

Non dedicated card... I just tested on one of our GTX590s (dual gpu on
one card) just rendering off one of the cards and it is the same
(tried both cards individually). GPU usage bounces all over the place
but when running it through bpy.ops.render.render() or via command
line it is 100% consistently.

These machines do not have a monitor attached as they are headless
nodes... accessing via VNC. Same results as on our artists

I can provide further testing later today if needed (two GPUs in one
machine, one fully dedicated CUDA card)

*>* samples as stored in the file.
*>>* We have noticed that F12 renders are not the most consistent measurement
*>* of benchmarks (under Win7 & CUDA at least), and that rendering via command
*>* line / python produces a more reliable benchmark result as the GPU
*>* utilization is always at 100%
*>>* The variation of F12 render times can be as great as 10%, at least in real
*>* world scenes.
*>>* Looking forward to your OpenCL developments!
