C2D E6600 still win in my opinion

1) Overclockability of E6600, mine can easily reach 3.2GHz
2) Price wise, E6600 will be slightly cheaper (as quoted by newegg)
3) Power Consumption, C2D 65W TDP while AMD 90W

Its nice to see AMD came up close to E6600 but the X2 architecture is going old and it is already reaching its limit.
