Considering that on the box it says ''Armor, then there is no ''Right'' way, they spell it Armor in America, and over there they spell it ''Armour''. It all means the exact same thing.
There is no difference really, so this discussion is moot.
also EVGA is going to be dropping the prices on the 8800 and 9800 cards in the next week so you my want to hold off till then. for what your paying for the 8800 you may be able to get 9800' for close to the same price.
