I am purchasing a new PC, and trying to find something with a 64 bit processor that will run Fedora, Red Hat, and/or Suse. I am trying out different distributions before I make a final selecion.

Which processor(s) will work?

-AMD Athlon64 2.4GHz
-AMD Sempron Athlon 64 3300+ 2.4GHz
-AMD Athlon64 X2 4400+ dual core 2.2GHz

Any good thoughts on packaged PC deals? Lots of smaller companies offer cheaper builds, but no hardware warranties. Maybe an HP? I would like to begin doing graphics work and work on programming projects.
Thanks,

I don't have a 64 bit cpu (Will do by the end of this year or start of next though), and it should work so long as you get an x86-64 bit version of the distro. I am led to believe that x86-64 is backword compatible, so it should work anyway.

The 64-bit distributions are still experimental. Until gcc gets better compiling program for 64-bit or K8 processors, I suggest waiting. AMD's 64-bit processors can still run 32-bit programs with out breaking a sweat. The Athlon64 X2 will be better for you.

For you or your bank balance?
