The address space (4GB) issue can be worked around with the bigmem kernel (I think the server kernel in Ubuntu). Speed wise, you'll see a difference in some apps and none in others. Multimedia, especially video, is one area where 64bit gets a small boost. Still, you're not likely to ever see anything close to even a 10% difference with 64bit, so it just depends how much the convenience means to you.<br>
