when we get x64?Like everyone here has said, it's not possible, but it's worthwhile with a system like yours. Go for it!
If you aren't in a rush then just wait till you get the full version of Windows 7 and then go x64.
You can use Windows East Transfer for backup most of your files and settings:

However... it won't work for moving applications, so you will need to re-install Office etc...
IIRC, you cannot use a WET file to go from 32 to 64, or vice versa.
1. I can't burn a DVD! CD Burner XP is telling me that my DVDs are of poor quality, or something of the sort. I'm gonna try using Nero and see if anything improves. :/
