I know there are a plethora of people asking this question because I've read a number of them and am still confused. I have an i3-2100 with 16gb of memory, and an i5-560m with 4gb in a different computer. If I want full 64 bit processor support, and full memory support, should I be using the AMD64 or the Intel x86? I've been using the AMD64 because I saw 64 and assumed that's the one I want for my 64 bit processor. However, reading the descriptions, it sounds like I may have wanted to use the other one. I figured if I used the wrong one it just wouldn't install.

Which one is the correct version for my uses?

You should always use the 64-bit version if your CPU supports it.

64-bit (x64) has many advantages over 32-bit (x86). Also, 64-bit CPU's have backwards compatibility for 32-bit.

Read more about 64-bit on Ubuntu's wiki for example.

One problem may be that you can't run all 32-bit programs on your 64-bit Ubuntu by default. This can be easily fixed by installing the 32-bit libraries (which is explained on the wiki page I refered to).
