I can add to that history of AMD/ATi lies:
I had a Rage Fury MAXX back in the day, and after a year of very poor support they dropped it altogether and I was out $300 IIRC.

They basically said they couldn't figure it out and gave up.
I also remember when HardOCP re-named the Quake executable to "Quack" and showed ATi had put IQ lowering code in the drivers specific to the game to dupe buyers into thinking their cards were better than they were.
AMD used to make all kinds of false claims about their "3DNow" patches and FP performance on their processors.
For that matter I could probably dig up similar on intel.
So basically all companies lie, exaggerate and make mistakes.
Smart people don't say "They lied/exaggerated/were wrong once, they can never be trusted again".
Have fun gaming with your rubber ball and jacks if that is the rule.
