I have been using fedora for a long time and this site unoffical
fedora faq alway helped me alot.
http://www.fedorafaq.org/#about
In the instalation page to figure out which to download on unoffical
fedora ( i have a sempron )
i386 - If you have a Pentium or Celeron (meaning any Pentium or
Celeron, including a Pentium 4, Pentium M, etc.)
x86_64 - If you have a Core Duo, Core Solo, Opteron, Athlon 64,
Turion 64, or Sempron. (This also includes the new "Intel Mac"
machines.)
* ppc - Any modern Mac that's not an Intel Mac.
BUT on the offical fedora
