Hello everyone!

I've recently decided to "downgrade" Ubuntu 12.10 on my laptop to Ubuntu 12.04. This is an older system (specs below) and I was wondering which flavor I should install; 32-bit or 64-bit? Based on my hardware I'd say 32-bit personally. But I've read a few things today that are making me second-guess myself on that decision. I'm looking to get the best performance I can from the 12.04 release; and I'm not 100% 32-bit would do this. So that being said, based on these specs, which version would be best? 32-bit or 64-bit?

I didn't find the right solution from the internet.
