You're comparing a 366mm2 chip (the 380/X)
with a 227mm2 chip (the 960)
Obviously as a consumer you are interested in price first and foremost, but from a business/profit point of view, that 960 is wiping the floor with the 380/X
First rule of the illogical Nvidia fan on any forum.
1. Never paint anything AMD in a positive light and when you don't have an argument just deflect the discussion to an area where Nvidia is teh aswum, even though it is irrelevant to the point being discussed.
