ATI don't produce better cards, they produce different cards.
Sometimes ATI leads, somtimes nvidia, and it's not only about the drivers.
I consider myself eco friendly - I believe 100% in nuclear power, that's also what I have(you even have to tick away water energy in Switzerland).
NP maybe is not the final solution, but it will do until we got the fusion under control.
Now, I really hate Ati for the sole reason, whenever they come up with a new driver, it may increase fps for some games, but same time produces new problems, problems which have been thought to be already solved with the previous driver.
Nvidias are like V8 engines, loud, consume a lot, generate a lot of heat, but reliable.
Atis are like boosted up mini displacement engines, cheaper at the gas station, but the require a shitload of maintenance.
(and once you got it back from the garage, you'll have to deal with new issues...)
nv ftw.
