As to the lawsuit - I think it'd be plain impossible because it's such a complicated matter that there're no experts who can explain why exactly a card with better specs performs the same as a card with quite a bit worse ones - only nvidia's engineers know.
That is the thing, it is all based on people making assumptions. There are people who know how it works. There are engineers who sit around with nothing better to do than to hack the hardware. There are people who write custom drivers for Nvidia cards. You can't go off the opinion of somebody who installed a driver that didn't work correctly and called foul.
It is such a major accusation that there would be warrants if
any shred of evidence was uncovered. It is illegal for them to do that as there are consumer protection laws that specifically cover this scenario (the Federal Trade Commission Act comes to mind). Do you really agree with the rumors that a 11 billion dollar company that is on the leading edge of graphics technology wants to cheat you out of a few dollars with a cheap trick that anybody with any PC knowledge would figure out immediately?
