The extigy is a card to be avoided unless you're using a laptop. It bootlenecks all the card functions through a USB port, reduces a lot of the quality.
The drivers for the XP are great, and more importantly Hercules (or Guillemont) are really good about updating drivers, with extra functionality.
As for gaming, the Creative cards have full support for EAX wich most modern games use, including there new EAX3 which they haven't released to other card manufacturers yet, but be assured when they do Hercules will be the first people to offer updated drivers for it.
In short, I have a Game Theater XP, and I wouldn't want anything else if I could.
