My point is also that...AMD new turbo Core will not work properly in 890FX boards due to the higher power requirement of the higher turbo core frequency. But if if you are a overclocker, normally turbo core needs to be disabled for better stability and it does not bring any earth shattering difference in terms of performance. Same applies for automatic underclocking features as ico mentioned.
Suman, 990FX is just a rebranded 890FX with some better compatibility with Bulldozer, proven in every review. Check guru3d, tomshardware, hardocp or Anandtech and it does not bring any out of the box features, missing in 890FX chipset. They are basically not at all for long run and going to be replaced by FM2 socket. They are here to support the transition period of AM3 to Bulldozer transformation.
So if anybody, buying a new AMD based rig, AM3+ is the way to go but people having existing 890GX or 890FX based rig, no need to upgrade it, at least for now.
