Kadahaf its a typo, the only AMD XP cpu that runs at a 2.08 GHz frequency is the XP2800+. there is no such thing as a xp2900+ as far as I know. I google searched it and at least one other person bought that "xp2900+" off tigerdirect and still thinks he has a real 2900+. you could however overclock your processor to equivalent xp2900+ speed by increasing your cpu external frequency or FSB.
maybe I spoke too soon. seems like there is such a thing as an xp2900+ designed primarily for HP/compaq. I do not suggest getting it either way. They say since it's not a mainstream CPU most motherboard BIOS cannot correctly identify the processor by reading it's CPUID:
