FAIL, because of the time. They needed one whole year just to release this????
????????????????????????????????????????????
WHY???
I don't use to describe or define any NVidia product.
Then I can understand why you consider 6800 series a fail. Price/performance compared to GTX 460 is better but nothing spectacular.
I can't say how much money nV is making with GTX 460 but one thing is certain, they sell like hotcakes. So in that regard it's far from fail.
And I bet 6800 will sell just as well.
