Looks good, but people have been telling me that it would not make a noticeable difference from what we have now because the integrated memory controller will suffer more from relaxed memory timings than it can gain from speeding up clock speed with the new DDR2 specs. But the DDR2 800 and on up should be much of an improvement so don't get the 667 one. The Socket AM2 is next generation technology as Intel already exloit it and it is a change that is becoming increasingly necessary for the sake of supporting more modern memory technology like DDR2 that will become mainstream in mid 2006 and into 2007.
