@chimera201 oh yeah its mem bus is 128, it should be 132... damn.but even then he had no chance he bought it from a store, he didn;t have the scope to check the specs and verify whether its 6750 or 6770.
He could have atleast checked the part number it's written there on the bar code. Part number is the only way to uniquely identify a tech product
Same thing with PSUs. Corsair has made the low quality VS series PSUs that's only available in India and China. Since it operates at 220-240V u won't find any reviews of it since Americans operate at 115V
