IMO both the 6990 and the 590 are failed cards but I tolerate that some may disagree.
I wouldn't also go as far as slating Nvidia for the pricing as they generally put a significant mark-up on their products and yet their priced their lead card at the same level as the competitor. As for the UK pricing - no comment from me. False economy really.
I agree... that the 6990 can't top a "broken", "unworkable", "hot" and "loud" architecture with its supposedly superior design means its a failure I guess and the 590 its silly pricing when I've been using a similiar performance setup (GTX470 SLI) for months now and cost me half the price of a GTX590.
