Sorry for the silly newb question but I'm just getting around to upgrading my PC after a few years of neglecting it. I picked up a Gigabyte mobo with a Realtek ALC888B as the onboard sound. I've got an x-fi fatal1ty gamer from my old rig and I'm wondering if it's worth installing these days? Is the x-fi leaps and bounds better then todays onboard sound chips? Not sure if it matters but this will be primarily for gaming and hooked up to Logitech Z-5500 digital 5.1 speakers. The thought of hooking the onboard sound via an optical cable appeals to me more then the 3 RCA jacks the Creative card requires. I also hate the ugly flat cable that connects the front bay panel to the x-fi itself.
