Sempron 64 3400+? Don't be surprised if this is the Sempron's last hurrah. Maybe I'm crazy, but I can't see AMD pushing the socket 754 envelope much further....It'll make a nice computer, but it will probably be an orphan in six months. The Athlon X2 and Opteron CPUs will be garden-variety soon enough. Almost scary how fast CPUs become dated--almost from their release date, now!
