If you've got an Intel sticker on the front you've NOT got an AMD processor... anyway, I don't think there are any issues with Dells.

It's only a bit inconvenient for an hour or so if it doesn't work - make sure you've printed this thread off before you start, and you'll know how to back track out of it.
