Newegg has this sound card for what seems like a hell of a deal, only $25 after rebate with free s&h. i currently use onboard sound on the build in my sig. i'm not an audiophile but want my speakers/headset (both good but nothing top-of-the line) to sound good for gaming and movies. any advice? my default is that for $25 how can i go wrong, but i know a lot of people generally disregard audio cards as unnecessary
