Looking for a good, simple sound card for Sonar X3

I'm wondering if anybody could recommend a good, inexpensive sound card for me to use with Sonar X3. 
I've seen a couple of other threads about this, but most people are looking for things that have extra inputs, and that doesn't apply to me.
 
Basically, I just need something that has low-latency and good sound quality.  All of my music is done via a MIDI controller and internal soft-synths like Dimension, EZ Drummer, etc.  I'm not trying to plug in guitars, mics, or anything else, so I really don't need anything that has extra inputs or any other bells and whistles.  I'm a very basic user. 
I used a Sound Blaster X-Fi card in the past, and it was perfectly sufficient for my needs (well, it was after I downloaded ASIO4All), but as I look around various forums now, the general sentiment seems to be "avoid SB like the plague!"  So I don't know, maybe SB has gotten worse?  Are "gaming soundcards" necessarily bad, even if I don't need extra inputs? 
 
(Just to clarify the situation a bit:  I don't even have my computer yet.  Well, I have one, but it doesn't work anymore, so I ordered  new one, along with Sonar X3.  The computer I ordered comes with only "intergrated audio," which I assume won't be particularly good for recording anything, so I'm planning to upgrade it with either an internal PCI-E card, or possibly a USB card.)
 
Any suggestions would be much appreciated, thanks! 
 
 

+1, if you are using a USB MIDI device and only need playback, you may already have what you need. You may have to play with driver modes in SONAR to get the best response, like WDM or even MME.

Thanks, guys!  That's good to hear. 
So I guess I'll just wait until I get my new computer, and test it out with the integrated audio before giving myself a headache trying to figure out upgrades that I might not even need. 
 
(just to be sure I understand correctly:  Putting in a sound card wouldn't make the audio coming from my softsynths sound any better?  In other words, the audio I get from, say, Dimension Pro, will sound just as good with the integrated audio as it would with a sound card?) 
 
 

Well more accurately, the audio you are sending through your interface (external or integrated) will be as good no matter what interface you use, but it might not sound as good. That is because the electronics in the interface that acts as a transducer and amplifier of the analog data is not identical in all interfaces. So if you had a really "noisy" interface compared to a pristine one, you could tell the difference, just as you could if you used poor headphones or speakers relative to really good ones. But the digital audio data recorded from softsynths in Sonar will be pristine regardless of the interface. For all practical purposes, unless your integrated audio is really lousy, you will probably not notice a difference, and your recordings would be just as perfect even if you were listening to them via a cement mixer, as they stay in the digital realm. The same could not be said if you are recording real world sound via a microphone into Sonar, because analog noise from the interface would be rendered into a digital representation and would taint your recordings.

Pretty impressive for the price.

Your internal soundcard will re-produce ... OK sound.  Not much below the bottom level INTERFACEs, which is what we call music ADDAs.  Something to watch out for is latency - the time between hitting a key on a midi controller and hearing the sound.  This can be really long on a built-in card and disruptive.  You can try, but most likely you'll need a USB interface.
 
Lots of people here use the Focusrite units w/ success.  Many others bought Roland when they owned Cake and the natural thought was sonar should work.  It usually did.  Now Tascam owns Cake, and they have a new line that is very competitive.  No one but Craig here has used them yet, but really no company should have much on any others.  That goes for quality, too.  If everyone is designing an interface at $150 there simply can't be much difference in the quality - same goes for $500.  I can vouch for the $500 Tascam UH-7000, the older brother in the new line.  Superb sound, which anyone can use if they have the monitors, although the 1st class preamps aren't much use to you.  And it is a bit high on the latency.  But Tascam has new drivers coming from in-house for the rest of the line, so maybe they are better.  Perhaps it will defy gravity and trickle up to my unit.  But it doesn't matter what you buy, so long as you can return it if you have problems w/ it.  Since all interfaces work most of the time on different systems, it is likely if you have a problem it is some component combo in your computer that is reacting w/ one company's drivers.  The next company's will most likely be fine.
