PC Perspective just did a really nice look at CUDA-enabled apps:  http://www.pcper.com/article.php?aid=719.  The review highlights the versatility of the apps taking advantage of CUDA and focuses on Badaboom!

“Finally, we are seeing some better CPU usage scores. Badaboom chewed through all of our benchmarks and gave us the best CPU usage scores we've seen so far. The most impressive CPU usage score came during the YouTube 1920x1080 MPEG-4 transcode that averaged only 9 percent! That's absolutely outstanding considering most of the other applications we've reviewed were over 50 percent and higher. Handbrake was pretty much pegged out at 99 percent for every benchmark and was also much slower in transcoding every benchmark. 

We've got to commend Elemental for paying attention to how much the CPU was being engaged during transcoding. There's a bit debate right now between getting the best transcoding performance from utilizing both the CPU and GPU and or just using the GPU and leaving the CPU for multi-tasking functions. I can see it going either way depending on the user's needs.”
