Both of my copies were "DUAL", allowing me to choose 64-bit when I started, or 32-bit, had I preferred that. I thought all of them were the same as mine.
Let's see if we can define "bad". Is totally wasting money a bad idea? I would say so. Now, if you only had a 256 MB video card and only the 2 GBs of system memory, you would be getting a full GB of improvement. That would not have been as much of a waste.
