I know there have been posts like this but the ones I see are like 2 years old. I have the Audigy 2 ZS. It has been a great card for me with zero problems. I have been considering buying the X-Fi Xtreme gamer but would like to hear more up to date comments from people who have made this change to decide if it's really worth it for me to finally switch out my trusty Audigy 2 ZS. I'm running Windows XP Pro so would rather hear comments from these experiences. BTW, I'm running the Logitech Z-5500 5.1 speakers so would be using the SPDIF passthrough for digital (since these speakers do the decoding). Thanks
