Really appreciate it. I heard same thing too. I might stick to 8370 then. I have found some people have succeeded OC bit above 5Ghz mark with 8370 and watercooled. I'm lack knowledge about OC, and received only little help when asking at forums. So maybe my safe bet to get higher clock by buying 9590, while actually my goal just to reach proper 4.5Ghz safely. sob
