I'd love to have "superb 64bit operation" but don't know which programs can't be used on a 64bit system. I do know that I'm on 32bit right now - when I upgraded the RAM I wasn't able to use more than 4GB (actual amount available is a little less). All my programs work now, but which ones won't? Is there a way to tell?
Another question, how do you move all your programs, especially if you don't want to look for the registration codes?
