I recently bought a new computer to replace my 4-year old computer that stopped working. My old computer has a Creative Lab Sound Blaster X-Fi ExtremeGamer sound card in it. I didn't buy a new sound card with my new computer. The motherboard is a ASUS P9X79 LE Intel X79 Chipset. Also, I do use a headset (Sennheiser PC-350) sometimes. I also have some Klipsch THX speakers with subwoofer.
Will my old soundcard be better than onboard sound? Is it worth the hassel (and potential issues jacking in my headset) to use it?
Is there a compelling reason to buy a new soundcard altogether?

On board sound has come a long way and is good enough for most people when it comes to gaming. But the X-Fi is superior and I would recommend installing it if you have it already. I have the X-Fi Titanium in my build in my sig. There is a noticeable improvement in spatial sound when gaming over on board even when using 2.1 speakers or headphones.
Your old sound card is and will be way better compared to onboard sound cards. I couldn't stand the onboard sound card at all. Such poor sound came out of it so I went and grabbed the Creative SB Z. It's like day and night, I get much more clear, crisp and big sound like never before. My headset has literally improved 1000%. Keep your card and use it.
