my bad!!
Oh ok lol misunderstood you there. Well i checked up on the dell website and it doesnt mention anything about the manufacturer of the card other than its Nvidia based, i did however see a mention of BFG but that was for the 6800 Ultra overclock so they mite be using the same manufacturer cuz usually they get bulk deals with them. If i were you i would call up the dell tech people and see if they have the answer. Or maybe sumone else in the forum mite have an answer for you.
