Wall specular with dispersion - nice caustics

Hi!
-Wall specular settings:
reflection 0.632
transmission 1.000
IOR 1.683
dispersion 0.015
-PMC kernel settings:
32-specular depth
10k-reject
no caustic blur
parallelism 1
I have rendered on "new" GTX 580 3GB (after GTX 480 died - RMA replaced to GTX 670):
Amazing rainbow caustics!
--> I will ALWAYS use dispersion because the real-life doesn't exist any object with non-dispersion. 
NOTE: I'm not interested GTX 670 and I'm selling it due to weak CUDA performance.

*pat the head*
Don't worry I don't think it's anything personal!
I've not tested anything with the caustics yet, from your sample image it looks like octane gives very impressive results and very quickly

I personally didn't comment cause I didn't know what to say. I'm not sure what I'm looking at. It looks noises and messy and like it needs a lot longer to render. I don't see the amazing render caustics. As I said, had nothing positive to say, so did.
Other people may not have commented for different reasons.
