I was looking into buying a new cpu for my motherboard, and when I look at the best possible cpu, the motherboard's webpage (here) claims that it is compatible with up to a Phenom II X2 series, but my motherboard's manual says the best cpu that it is compatible with is the Athlon 64 X2 series, which is what is currently installed in it. Which should I trust? Can my motherboard actually handle a current cpu like the Phenom II X2 series?
