Time to buy the new video card

Everybody plays with training and recognition on a GPU now. 200x improvement on NVidia CUDA is worth time and money. Moreover that the sample code is already available.

Thanks to prym on #cmusphinx channel on irc for the link and of course huge thanks Chuan Liu for the article and a new project. It would be so great to see the similar patches for Sphinxtrain/sphinx4, it would be the killer feature.
