It's widely known that an Athlon XP processor is about half the price of an Athlon MP processor. I recently read from a computer magazine that an XP simply won't work in a multi-processor board, and furthermore that the only difference between the MP and the XP is that the L1 bridge on the XP is severed whereas it isn't severed on the XP. How the heck can AMD get away with that? I love AMD. Far cheaper than Intel, and every advance Intel makes, AMD seem to be there to go one better, but surely, If all you have to do is reconnect the L1 bridge, who's going to buy an Athlon MP, andhow can they justify twice the price for it?
