I just pulled the card and the backplate, and i actually found no fit problems.
After comparing the card I just assembled (I have pics if any of you are curious) and the backplates posted here, it looks as though the regular version and the FTW have been mis-packaged, I will let the support manager know about this so we can assist those who have had the issue and speak with our back end and get this resolved at the source.
Again I apologize for the inconvenience, and we will work to get this resolved for all of you.
**addendum**
I have informed the heads of US and EU customer service know so we can get this straightened out for those of you who have the incorrect backplates.
