Why did you even mention overclockability? If they clocked the hardware higher for you at the factory how is that a con that it has less overclockability? It is like buying an item not calibrated, costs you nothing but your time to get it calibrated but if you bought it already calibrated it would save you work.. that is a con for sure. (Talking the same price here for the calibrated and noncalibrated product)
