My take is that the sound card can make a huge difference, even if you assume you keep the same speakers and that they're no better than "low-end". People are pissed at Creative because they have some kind of incompatibility with the beloved Via motherboards, and more importantly because they killed the first real positional sound innovation because it was better than their technology, and in doing so turned a whole bunch of peoples' sound cards into paperweights and set the science of positional sound back four years, all because they wanted to have the most market share regardless of the quality of their product.
As far as Creative drivers, I know what people are talking about, because they recently stopped providing full downloads for any of their software, only updates - meaning that the only way to get your eax config panel, etc. (at least that I could find) is to install your win98 driver CD on your winXP computer, which results in something similar to duct taping a printed error message to the front of your monitor.
As far as sound card quality mattering, let's go back to SB Live! which is what you had to switch to if you had an Aureal 2.0 card and wanted to use anything but windows98 with an outdated directX, back when they killed it... The positional sound was very, very, markedly, hugely weak compared with the aureal technology. (I know there's at least one person on this forum who doesn't hear the positional effect, but come on, 19 out of 20 people can, so I don't expect any argument on this topic.) It didn't do well on occlusion, didn't do well with vertical placement, only did well with horizontal placement if you had 4 speakers, and relied almost entirely on the pathetic ability to add echo to stuff, which is one of the most annoying and abused special effects I have ever seen used in games. For more specific example, I could close my eyes in a game of half-life on the aureal 2.0 card, and could hear the accoustic difference between being in the center of the room and being in a corner of a room, could hear the difference between something being in front of me but obscured by a thin wall (fully occluded sound path), in front of me and behind a corner of a wall (indirect sound path), or in front of me with no wall (direct sound path), and it even carried those accoustic differences if those three situations happened in an enclosed room or out in a field or canyon. All the creative cards did at that time was load new echo settings into their dsp when the character passed through a polygon from one room to another. In short, the effects of a Creative Live! card could be duplicated by connecting an echo effects dsp box from your local performance music store between your soundcard and speakers, and having a little gnome adjust the knobs while you play your game.
Now, Creative has gotten better technology since then, but that's still very solid example of how a sound card can make a huge difference. <i>HOWEVER</i> I have to say something about the frequent reccommendation of some cards here... I've been fighting with my new game theater XP for a week now, cannot get any reasonable amount of help from Hercules, cannot get onto the Hercules forums because their registration system is broken, their knowledge base seems to be outright wrong in its solution to my problem, and they have no 800 number to call, you have to pay for long distance. On top of that, the Hercules knowledge base states that their system has some rather strange limitations involving the digital inputs:
<A HREF="http://us.hercules.com/support/readtechnote.php3?id=702&prodid=17&c=1&p=0" target="_new">Oh, you wanted working inputs?</A>
<A HREF="http://us.hercules.com/support/readtechnote.php3?id=721&prodid=17&c=1&p=0" target="_new">equalizer? what equalizer?</A>
Furthermore, it doesn't seem to have the ability (as Creative cards do) to mix "normal stereo" sources into the full 3D sound field, a.k.a. playing a line-input or analog CD audio cable using your full set of speakers, instead of just the front 2.
<A HREF="http://us.hercules.com/support/readtechnote.php3?id=706&prodid=17&c=1&p=0" target="_new">Look Here.</A>
With all these problems I'm having, and the limitations they talk about on the knowledge base, I'm wondering if I shouldn't go look for a Creative Audigy or Extigy. Got some shopping to do, no matter what, because if my problem isn't solved by thursday I have to take the gtxp back regardless or I won't be able to get a refund.
