Check the link below for piccies on how to identify a fake XP processor. Over-Clock.co.uk (my fave store ) has just recently intercepted some fake XP's - very strange - AND from two suppliers. I wonder what's going on? And is there anything like this going on in the states? Difficult to tell for large outlets such as Neweggs i would guess, but as O-CuK is small, they check and guarentee CPU steppings which is how they found this fakes. Craaaazy!
