The big issue with Creative is the so called ASIO drivers are the worst in history. I had (still have in my office computer)  the Audigy II, What will happen is your tracks will never line up! This seems to be a universal problem with all Creative products. I  myself and other tying to use the card have found there is no way to make a multi track recording with those drivers.
It works perfectly fine for stereo recordings etc. And you'll have even worse timing issues if you try and use VST instruments. 
My card is a PCI with a breakout and has some great in out options. It has a very low noise floor. If it had good ASIO drivers I would still be using it as it has SPDIF input for my 01v. So please, do yourself a favour and move onward and upward! 
 
You don't have a mike pre amp, that is also your problem. You will need an interface with a mike pre amp. That it. The audio interface is the heart of all DAW recording. The drivers are paramount! 

Extreme Gamer (Creative Sound) is the first card you can use for recording. The Audigy II (which I also have and thought I could use) you can not record on. Yours maybe a bit better but the better is actually geared for non-professional in a sense use. Ah, there are other things, like it only works at a clock rate of 48000 Hz sample speed recording (although you can record at other speeds, it does not change at least in the first card you could use - the Extreme Gamer). So let's say your card is a bit better and newer than 2007, but then like me, you may not have found out anything yet about the recording world, and think it should sound okay.
 
Well, why I keep this up (is because I have not done it over and well it is not that good anyway, but it is the Extreme Gamer and for music (maybe even voice) it sounds like this:

Now a way more expensive regular audio interface for recording and such (does not mean I play any better or mix any better either or anything else), but even with a less expensive audio interface (and I do admit there is some other equipment along the way to help with the voice, and a new more expensive microphone (sennheiser - condenser MK4) and channel strips for my recording meanderings and goofing off just to record:

The evidence is clear, because even though I did not use anything with the extreme gamer cheap card from Creative and there is Emu some people do use and can like which is actually a real audio interface, a sound card like used to play computer games is a sound card more than the other which is a real audio interface for serious recording.
 
But for anything else, that does not still mean that I will be able to sound better in the future either. But then I am not a rock star, don't intend to be, and just fool around sometimes and really did not spend thousands of dollars on it either.
 
But some people I know may like it, or else they can kid me about it, whatever. Like I really like a lot of things give all that much about it. It's all relative, but I am alive in a day and age where I do not have to listen to tape anymore, and anything else is in the ears of the beholder.
 
Ah..................well, that's about it.

 
 P.S. ( the guitar in the extreme gamer recording is my synth ,although the chords in the song on guitar are a real - cheap guitar and that is another practice session).
 
The second recording has a better guitar and maybe a bit better playing that is all guitar. Which is another practice session or actually a lot of practice sessions.
 
And you can buy all this stuff at some store, whether it is Cakewalk, Roland, Gibson, TC Helicon, or Presonnus or any other manufacturer, like FocusRite, MOTU, ah, well, you can look them all up.
 
 
 

"Although many USB sound cards are designed with audio production in mind, the X-Fi 5.1 Pro is a more modest consumer affair. It can record at up to 24-bit/96kHZ but there's no dedicated ASIO driver for low-latency recording. It's fine for internet telephony and voice chat, but don't expect to be using it to record the masters for your next album." 
 
This is just a quick look at some reviews. What I was after was if there were in fact drivers for it. Any interface that uses Windows legacy drivers will not work well Sonar, Fact. I was also curious to see if it had SPDIF input. Anyhow it's a gaming and movie oriented device. Move on.
