most likely not. If you read the most warranties carefully, they state that they will replace within X amount of time. for an equivalent or higher model or something in that format. so lets say they dont have an 6600 in stock, and the next model up they have in stock is an 6800 they are going to give you that. it would cost them more to make 1 single card or locate 1 single card that its cheaper for them to give you a higher model and make you happy at the same time. not to mention it most likely cost the company the same amount of money to make both cards.
