Should i Install 64 bit RC1 to a twin xeon 1.7 box

Better off for what? It is pre-release software which you should not be
using for production or primary home use, so it does not matter from the
standpoint as a user. Since you will be looking for issues to report to MS
or evaluating how your own software fares under Vista, try either or both.
It would be more helpful to MS if you evaluated x64 since the installed x64
testing base is far smaller than it is for x86 and x64 reports would be much
liklier to be useful.
