64bit is solely needed for nothing more than being able to address
memory addresses above 4GB so there's no need for hardware other than
that between the CPU and the RAM to support 64bit.

Don't you need software that can utilize 64bit too? I mean other than the
OS. I'm asking about something I neither use or know didly about.

Wrong again. It may refer to memory address lines only but can also refer
to the width of the data path between the CPU and memory. Obviously, things
get to memory and back a lot faster on a wider bus.

In other words, any MB that supports a 64-bit CPU is the best that is
available, and the best that you need. No other changes needed to
fully support 64-bit.

I think your software and OS must support 64bit arcthiture for you to derive
benefit from that hardware capability. Remember SSE, SSE2, SSE3, MMX and AMD
3d Now? http://en.wikipedia.org/wiki/Streaming_SIMD_Extensions
If it doesn't say it on the software box then you don't benefit.

Perhaps you should learn to understand what you read...

Correct.
All 64-bit components? 
Linear Mode
