I am not going to buy one.
Not only is it too expensive, but the 9800 XT or GeforceFX 5950 Ultra would actually be best to buy due to the DRAMATIC price drops that they will be seeing due to the new video cards coming out.
So I am going for the 9800 XT for sure.
Then, once something happens to the 6800 Ultras price or the new Radeon card comes out and its price drops, I will consider renewing my card.
