As most of you are no doubt aware, CUDA is a Nvidia software development kit, so as it currently looks, this will be an Nvidia-only benchmark.
well personally i don't know much about ati/amd at all, BUT cuda is a framework for designing software to run on nvidia gpu. anyone can get cuda and develop anything they wish. i know a guy who made md5 cracking utility with that. and the speed is amazing. 150Mhashes / sec with my configuration. compared to 9Mhash/s on most powerful consumer cpu ( i don't remember exactly which, i know it was intel though )
