The lack of muti-threaded application can only be blamed on lousy developers. There's a game that called Alan's Wake for PC and it will be the first pc game that utilized all 4 cores.
quad core and octo core useless?
Or do you mean useless developer? 8 cores too hot you say? Why do you think cpu cooler exist and why every 2 years there's a die shrink? Aka nanometer. If anyone know the Intel's Tick-Tock tatics, then you should know that Yorkfield and Wolfdale are only just a Tick. The Tock will be Nehalme! Some said, it will be more amazing then the transition from Pentium 4 to COre 2!
