I wasn't going to buy it but the promo pic and the price did it for me - couldn't resist. I installed the OpenCL version of Lux. I first had to update my graphics card driver to support it. There is definitely going to be a learning curve, but I like the interactivity a lot, and I don't find it very slow. Perhaps OpenCL does make a difference to the speed?
