After chasing down the link to the creative Asia site I put in a previous post, I figured out the .asp files I was getting were actually zip archives of pdf documents. Apparently Creative has been making motherboards with integrated Live 5.1 sound for about 3 years, and the boards at least listed on the site go from M000 to M011, with about 3 versions of the case. The M004 used the BX440 chipset, and the M010 used the BX820 chipset, but neither seems to be an exact match for the board TigerDirect is offering (which says agp is 2x).
I hope somebody that knows more about intel PCs goes to the creative asia site and figures out more. One point I noted is that this unit is more than the normal Live 5.1, it includes the digital I/O panel (the upper row of connections) which Compgeeks wants another $29 for (live drive appears gone from the geeks). Another point is that many of the connectors require adapter cables which don't appear to be included (midi and digital optical for example).
Bottom line for me, and I am still wobbling, is no.
I want a Live 5.1, but I want it in my FAST new game system, not some old Pentium II/III running 100 mhz fsb. The notion of $150 my cost of sound card that I can't move to another system just eats at me. Better to buy a Live value and the geeks I/O panel.
