Dual Core and 32/64

[hermanaa]

I run Ubuntu 6.06LTS with no problems.

I cannot upgrade to any higher version.
 Installations do not complete.
I tried 8.04, both standard and alternate.
I tried 8.10 rc and final, both standard and Alternate.
 (I see no way to upgrade ....)

I have used 32-bit. I did not try 64-bit.
Can I (should I?) use 64-bit Ubuntu OS-es with
 this computer?
