how to upgrade to a 64-bit mobo?

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,


Millions(?) must have done this but googling left doubts.

I'm thinking of upgrading my EP-8VTAI 32-bit mobo to an ASUS M2N-SLI 
which is 64-bit.

I now run one Sid system that is pure i386.

What is best?

1. install the ASUS M2N-SLI into a new box and keep the old box.

2. install the ASUS M2N-SLI into the present box but then I have 4 HDD's 
with only 32-bit Sid.

Many must have faced this question. Pointers?
