5.1/6.1 Sound - Do you use it?

Just curious as to how much use you people out there with 5.1 or 6.1 sound systems on your computers get out of them. Are you watching movies? Do games utilize these? Which ones? What speakers are you using, and do you recommend them?

I use 5.1 logitech z-640 speakers. I picked them up for $60 and got a $20 mail in rebate. For 40 bucks I love them . I use em for gaming and watching dvd's, I do both alot. Not the best Ive seen but I recomend these speakers if your on a budget.
