If you have a 64-bit processor, and you install the 64-bit version of Ubuntu, then yes.

32-bit operating systems can't address more than 4GB of memory, and this includes memory addresses other than your RAM, like graphics card memory etc, so you get something around 3GB of accessible RAM.

(Well, you can always use PAE-enabled kernel like the server kernel to work around the limit, but PAE has it's downsides as well so I'd recommend going for real 64-bit instead)

McDuck is correct, if you want to be able to use more than 4GB ram you will have to change to the 64bit version of Ubuntu. Be sure your CPU supports it though!

AMD Phenom X4 9550 Asus M3A78 hdmi DDR2 pc6400 800 mhz Geforce 512mb video card. I use this machine for video and music I have a 1.5 tb drive that I use as storage. This is fast on burning and video editing. Do you guys think the 64bit version would be better to install?

Definately yes. You want the 64bit. It'll have to be a new install though, because you can't upgrade from the 32bit to the 64bit.

Yes, your system definitely supports 64 bits, and if you plan on working with any video/audio on Linux you'll get a nice performance kick from using 64-bit operating system in addition to extra RAM supported.

..besides, these days stuff like Flash and Java are easily available for 64-bit Linux as well, so there isn't really anything to loose. ;)
