I accidentally installed the 32 bit version of ubuntu 8.10 before I remembered that I have a 64 bit amd processor.

Does this make a considerable difference in speed or anything else?

from what i gather its only really useful to use 64bit when your doing serious number crunching or want to use more than 4GB ram..

i have 64bit cpu and using 32 bit ubuntu...

for general usage there's little to no difference.
unless you're doing lots of video encoding or anything else CPU intensive, I wouldn't worry

Generally, no you wouldn't notice an extreme difference.

Bingo.

For most folks-unless they are wanting to run Photoshop type applications which needs lots of ram and scratch-disk, as well as actually having 4GB+ of ram--they won't notice a difference.
