Can you run OS X on an old Windows machine?

[iamom]

I have a PC running Windows XP with an AMD Athlon 2 GHz chip in it and 1 GB of RAM. Does anyone know if OS X (i.e. 10.4 Tiger, for Intel-chipped Macs) can be installed on that machine? Or does the fact that I have an AMD chip and not Intel preclude me from doing this?

Thanks in advance for your opinions.
