Ugh, skip on the overpriced and under performing Creative cards
I am assuming you either have a dedicated headphone amp or are using easy to drive cans?
If so, look into the
ASUS Xonar Dx (PCIe) or
Xonar D1 (PCI).
Both have top notch sound quality and a good amount of features.
They also offer a very good implementation of Dolby Headphone, which will allow you to game with virtual surround sound on your headphones.
The
Auentech Bravura is also a good choice if you can afford to wait for the MIR.
Sound quality is fairly similar to the Dx/D1 and the addition of a dedicated headphone amp is a nice feature.
The biggest downside to it, besides needing to use Creative based drivers, is that it is not truly a X-Fi based card.
Instead it uses the
CA0110 chipset (a PCIe port of the circa 2001
Live! 24-bit's chip) that is quite gimped in terms of processing.
In fact, it does not support EAX processing at all in hardware, and only to EAX 4 through software.
In contrast, both ASUS cards (not boasting Creative chips) support EAX 2 in hardware and up to EAX 5 through software.
Note:
EAX is pretty useless now.
Defiantly do not base your purchase decision on the cards EAX support unless you are predominately playing quite old games.
Either will treat you fine.
If you have low impedance cans I would recommend one of the Xonars.
If having a bit more amplification is necessary, the Bravura is also a good choice.
