No, 754 is not on it's way out. It will still be around for sometime. That's where the Sempron processors come in. The upgrade path with 754 will not be as good as on a 939socket however. I currently use a 754 3200+ clawhammer(but that's because i bought it before 939 was out), and it runs great. some people achieve better performance off a 754 sometimes( 'some people' ).... If you plan on wanting the latest stuff that's out, get a 3200+ winchester(939) with a cheap mobo, and later upgrade your mobo to a new one that supports new features like pci express.
