Here is the link http://www.m-audio.com/ to get the updates.

Well Nelly the review you probably come across is for the Revolution 7.1. There is quite an amount of reviews for that certain card but i am sure you shall have a hard time finding a proper review for the 5.1 model. According to some articles l have read at the time l purchased the card say that the 5.1 uses a better quality DAC allowing better sound quality than the 7.1 version.
Now answering your question, l wouldn't go for this card if gaming is your main focus. It's suited for people who listen a lot of music and the sound quality was quite better than the Audigy 2 ZS i used before.
As for movies, decoding is done by the CPU but the hit is very small since most people today and especially in this website are using very powerful systems.
