Wow, EXTREMELY close to my build. I got a Seasonic 550w though, and a 7900gs instead of the 8800gts. I've read onboard sound is pretty good so unless you're a hardcore audiophile or gamer, you don't really need the x-fi. As for the dvd burner, the Pioneer 111D is supposedly really good. The newer version, 112D, is out too btw. Also be sure to get some thermal paste like Arctic Silver 5.
