full Backwards compatable, like you can run x86 bin on x86_64? or not? becuase my processor will run both os's... and I like compatability

afaik you can use x86 packages, libraries and so on, but they won't use the 64kbit possibilities of the processor.

Yes, Ilja is correct. On a x86_64 processor (AMD64) you can run x86 binaries and libs in your x86_64 OS, they just won't run quite as fast and also are harder to setup (with multi arch libraries).
