EDIT: sorted now thanks. There is a small possibility that I could get an X-Fi xtreme for approx €30-€35. I need to find out which version it is first, but I have questions anyway as I've no idea if any of these cards are worth having. I would install the card in an old system, uses I have in mind would be retro gaming, some music listening , and some TV watching. Is there any driver support for Windows 7 & 8, even if only 3rd party drivers like DanielK's? Is there good (or any) support in Linux? Which versions have EAX 5.0? Should any particular versions of the X-Fi Xtreme be avoided? are any particularly sought after?
IIRC the X-Fi Xtreme Audio doesn't use the X-Fi chip all the other models use so avoid that one. The Xtreme Music and Xtreme Gamer cards are fine.
Thanks for the reply, card is no longer available so that puts the kybosh on that idea, at least for the time being.
