Would I get 2 free games if I bought this GPU? :D (newegg special offer)?

It is true. Graphics cards come with bundled games all the time. My friend's card came with Metro 2033 back when he got it. What's likely there is that for the one that requires registration, it'll ask for your card's serial number or something and that will determine what game you get, so what card you get will determine what game you get.
