Creative Sound Blaster X-Fi series driver is not that good, because for working for these drivers you need to have nForce4 chipset mother board. If you do not have that then it will not work for you. It is true that this driver is WHQL certified. If you choosing then I will not suggest you for this because it is not having support for OpenAL 64-bit. One positive point related to this is that you can use AudioConsole if Equalizer is supported.
