I don't know if this has been mentioned, but you'd probably get a bigger
performance boost by using a SMP kernel rather than recompiling a
non-SMP kernel for AMD.  SMP (Symmetric Multiprocessing) will take
advantage of hyperthreaded processors and you should always install an
SMP kernel on a modern computer.

On Fedora, for example, there's not SMP kernel option in the installer
but there is a SMP kernel included on the CDs for you to install
manually.
