I think we can all agree that listening to a wasp/bee going around in circles demonstrating 3d audio is one thing. (one of the wizards for onboard)
Listening to music is another.
But the crux of it is the depth for the likes of 3d gaming and, for me, 3d movies. ApocalypseNow`s helicopters on the shore, or Heat`s shout-out scene, played through onboard and a simple creative 5.1 is just totally different.
Personally I don`t go for eax, that`s not important to me on a card, but that aside, it`s really a question (as usual) of what u`r gonna use the pc for.
I think this can change tho, and the market is open for gaming/htpc pc-motherboards, with excellent quality (well `great`) gfx and great sound, legacy free and made really small. To sum it up, I`m looking at AMD/ATI/Creative. Not the onboard stuff of today, but something they can pursue that would make a gaming/movie pc something the size of an XBox, and maintain a quality.
But I hear u say why not just buy an XBox... which is a fair comment, but although the XBox gen is a tremendous platform in it`s own right, a PC box, with all it`s advantages of not having to buy expensive unique hardware that only works for it (I`m thinking USB devices, drives etc) is a huge advantage. - and u don`t have to then have a pc and an xbox prehaps. meh.
hmm something for AMD to think about maybe.
