Now I don't want to imagine how bad it would get if nvidia got even bigger.
Nvidia is very tiny, they can only get bigger (or go bankrupt).
WTF is this about N-Vidia buying out AMD, I dont think that would EVER happen.
You're probably right. It would be more likely that AMD buy Nvidia, and not the other way around. After all, AMD makes about 3 times the revenue Nvidia does.
