zalbard: Im talking about hard OC, Im not as 90% users, push to the limits. After is Ivy very hungry with high voltages. Of course we can have two situation:
1) 1.3V 4600 MHz Ivy
2)1.45V 4750 MHz Ivy (+150 MHz, + around next 50W)

The example of 1 is more efective, ideal for 90% users
the example of 2 is for enthusiast, who doesnt care much for long product life (1, max 2 years will be OK for him) and for power consumption

So...FX-9xxx is OC edition of Vishera at stock. In limited production for hard enthusiast. And from my point of view is not bad, Il be happy for theoretical 500W CPU with 10% higher performance than 3970x i7@ 4.5 GHz. Because this could be wow efffect for me. Power consumption in this case is the last one. Btw. 500W CPU is really unreal for cooling and most PWMs :-D
