Regarding the 8800/9800 cards. MANY people purchased 9800GT's, GTX's, with 8800 stickers underneath the new 9800 sticker. This happened OFTEN, not just an odd occurrence. They got lazy because ATi was nowhere near the 8800 performance at the time.
It happened and I even brought it up when I was looking to replace my old 7900GT. I was looking at BFG and they had more "sticker issues" than any other Brand. I stuck with eVga and am glad I did. I RMA'd my 7900GT (the Samsung RAM) and received a $160 8800GT without a single question asked.
I'm looking at the GTX 280 at maybe in the Fall, but I still love my 8800GTS KO.
