Actually, I'm a bit unsure. My sound card is a simple Titanium X-Fi, not a Fatal1ty one and I've heard a couple bad things about creative drivers, though the card is supposed to be decent. I'm not sure about getting a receiver/amp for a 2.1 system only, but then I could output the audio via the video card with an HDMI cable and get passive speakers, which as I've read somewhere, may be a good decision(and give the card away or something). Ideally I would buy the speakers as a set, designed together.
