It's practically the weekend, which means it's practically time for you to drop some knowledge on the world right here at Ask Engadget. We've got a good one queued up this week, so have a peek before sending in a question of your own to ask at engadget dawt com.

"I was hoping to get some help deciding which sound card to buy these days. I need it to work with Windows 7, and I'll be using it mainly for gaming and for casual music. I have a reasonably nice 5.1 speaker system. It has to be PCI Express (of course). So yeah, are the Creative cards actually what I want? Or is there another brand I'm not familiar with that will suit my needs? Or should I not even bother, and just go with my motherboard's sound output like I'm doing now?"

So, friends -- is a sound card even worth the cheddar? If so, which one is the best to slap down some hard-earned cash for? Do tell.
