[LAU] Pros and cons of 64 bit Linux

I am setting up a new system, running an ATI Radeon video card and a
RME PCI sound card. My box can run a 64 bit Linux operating system,
and I already have an Ubuntu 9.04 x64 installer ready. I wonder what
are the pros and cons of running a 64 bit Linux system nowadays. This
machine will not be used only for audio and video work, also for
blogging so I need that the Firefox web browser and all extensions run
flawlessly. Any info will be very useful so thanks in advance. Compiz?
Java? Flash?

Cordially, Ismael
