The Q9550 is supposed to replace the Q9450 at same price point with Base higher clock and .5 more multi.I was just curious about the Q9650 because I think they are going to stop producing 775 chipsets I would get a as high enough that would do me for 3 or 4 years.I would probably upgrade at whatever is 2 generations above the nehalem (sp?).Have to get a new MB anyways so I wouldnt count on getting one a of the extreme 775 as from what I have seen they dont lower the prices on those much anyways
