I want to install Ubuntu 64 Bit on a i5 CPU, but I'm not sure how the 64 Bit version performs now.

How good is the application support for it? Are there any issues to be aware of?

In general, is it better to go with a 32 Bit or 64 Bit operating system?

Short answer : 64 bit.

If you want a longer explanation and some documentation about the topic, see ubuntu-64-bit-vs-32-bit.

I use 64 bit Ubuntu/Kubuntu/Mint/Arch for years. 64 bit version has become good enough and as people already said you can install 32bit library's easely:

sudo apt-get install ia32-libs

Another clue that could convince you is that from next release Ubuntu will no longer recommend 32-bit versions when you click on "Download Ubuntu" because the assumption is that most people have hardware that is capable of 64 bit computing. You are ready now (I hope you don't have less RAM than 2Gb with such processor).

I haven't encountered any 32-bit problems with my 64-bit OS for a few years now. I would definetily go with 64-bit so that I don't need to migrate later.
