There are now a number of media converter utils on the market that take advantage of both Cuda and Stream.
It would be a great project to have a top nVidia & AMD card, and play with Badaboom, Cyberlink Mediashow, FormatFactory, and Nero? I hear. Perhaps any others.
Do a comparison of a set video (a free downloadable one of course) and perhaps have the software people provide a sample of their software for the review.
Perhaps the software people would be happier as a participant if they were informed the process could be used as a global benching process for future hardware reviews.
Maybe a card manufacturer will provide the subject with a card from each camp to use. AMD & Intel cpus / i7 / 775...
It'd be a great adventure for some1 (love to do it myself, not sure about having the time tbh).
Being these days almost every1 has either an iPhone (or alt), htpc, PSP, etc or just for netbook/laptop viewing, media conversion becomes more and more popular.
