I understand that. Your card is also not identical to every other graphics card. Heat sinks can be constructed differently with centers of gravity at different points. The actual GPU chip can be closer to the front or further to the back of the card, resulting in the main bulk of the heat sink being in different places. Backplates can be more or less rigid, and some backplates aren't well secured to the card's IO shroud (which means it's just extra weight on the card, and not providing any rigidity with regard to being connected to the case, which is the real basis of the card's support.) Cards can have more or less heat sinks, (VRM, etc) more or less fans...
I think you get my point. Your card sounds awesome, and is probably fine. But it's not indicative of all cards.
