Is my vostro 260s (or 0gdg8y) compatible with i7 3xxx?

I'm looking to buy an i7 3xxx! I researched and saw that "lga" would possibly be compatible, but I have my doubts. I also saw this same question in the forums, but I didn't understand it right, because some said that, yes, it is compatible and others said that it is not. So I want to be 100% sure. (If you can, would you send a list of compatible processors?) Thank you!
