Are you kidding me man? He'll sure as hell see a performance increase, he'll see a massive increase in memory bandwidth with the memory speed being close to double, not to mention the instruction speed gained.
IMO intel sucks (sure, a billion fan boys would jump in here and flame me) and corsair sucks too, not that the brand matters
If you're going to blatantly state that a manufacturer sucks you should at least justify your reasoning. I'm certain this guy has a socket 478 motherboard and is not interested in dishing out the cash for a new platform altogether.
