Well it works for me with my 6970 and allows me to know were fire is coming from or foot steeps and such so yes i need it for better game play and ATI give that option though their video cards.. One thing is though their cards already have it so why are they only bringing it up now like if it was not there in the 1st place lol. And Free LOL, nothings FREE. It's one reason i will opt for a ATI before a nVidia card. I have used positional audio in my games for so many years now just that many don't realize they can have it or not in to such things. And optical output used to be a given for positional audio even back when i had my ABit mobo with a 3800x2. And to be honest i don't care about consoles and if they have it or not no good to me as seen as most only have 2-4 games that i will play on them in there life time.
