So, I have a computer with an i3 processor, which I'm pretty sure is capable of running a 64 bit operating system. Currently I have 32 bit Ubuntu installed on it. What are the practical benefits of a 64 bit operating system...is it worth wiping my system to install Ubuntu 64 bit? I am not a gamer or anything...basically this computer is used for very light tasks, like surfing the web, word processing, etc. Occasionally I might want to run a memory-intensive program, like Eclipse, or possibly spin up an Android emulator. What do y'all think?

Personally I install 64-bit on any machine that is capable of running 64-bit, there is no good reason not to.

As to whether it is worth the hassle of upgrading, that depends.
How much RAM do you have?

64-bit takes more RAM from your system and it gives you a speed boost. My advice is, if you have at least 3GB of RAM, go for 64-bit and the speed boost.

If you have 4GB of RAM or more, the regular 32-bit kernel cannot use all of your memory. The pae kernel is 32-bit and it can use more than 4GB of RAM, but it is also slower than even the regular 32-bit kernel.

Windows games are 32-bit mostly. 64-bit doesn't help you play video games. Video encoding is where people most commonly see the biggest difference.

If you already have a stable system, it may not be worth messing with it. The speed boost is small, so you decide whether or not you want to go through the trouble of reinstalling.

Moved to recurring discussion. As we get this question daily.

Linus does not like PAE or 32 bit.

Well, I have 8G RAM, but I'm pretty happy with the way things are running so far. The only reason I installed 32 bit is because that was the CD I had lying around and I was impatient to get my new toy up and running. I kind of wish I had been patient and made a 64 bit LiveCD, but I don't think I'm regretful enough to start from scratch.

Thanks for the input everyone and sorry for the duplicate thread.
