You using that with Win7? 64 bit? Any driver issues? Feedback on Newegg is quite poor for driver quality, but of course the complaints are "louder" than the good feedback.
Yes! I have many Asus Xonar all in 64-bit Win7. The only issue I have is with Skype and it's a known issue. It has you disconnect and reconnect if you host or join a chat...pretty minor IMO. On the flip-side: I use the Creative Xfi Platinum on my 2nd rig and it has the above stated issues. I'd rather the Skype not support, dc/rc, than to do the dance I do to play on this machine with a simple voice chat application. 1) disable X-fi enhancements and get them back after a reboot (that's basically everything an X-fi is about...besides mono sound) 2)Restart Windows Audio every time it gets above 200M 3) Don't Skype on that machine.
The Xonar machines I deal with are all fine in Win7-64. Even with onboard audio, I believe it passes off EAX 4+ off to the CPU just fine. There's spacial sound, great many number of voice channels, and everything one would want an X-fi for...and more. The only caveat is that Xonars need a separate power source...the floppy power cable. May be just PCIe cards as I have not owned a PCI Xonar device.
I was sold on the D2X (I should have said DX2 just to ruffle feathers of the nerd patrol)
on day one of using it (through great speakers and source media), and have used them sense in different forms. IF the GF know the difference, I don't care much...I'm on that machine here and there and then I care. However, if we're just talking about run of the mill $150 speaker sets and/or an aged dual core, it may not be promising. I've got modified Klipsch Ultra 5.1's for the secondary machine, and the primary has to be accurate...and we can't go into that ordeal here. There's other cards I've loved (Auzentech), but this one is the Chevy 350 if you will. I'm not swapping out chips to get it perfect. And it's a $100 PCIe card none the less!
Yes, it does 64-bit. I've got a lot to say about the undertones of the question, but I'll let 'em pass. This is my opinion of the piece of hardware here.
