It might be true if you work in NVidia's marketing department but in the real world no!
I've used both AMD and NVidia cards and I would say the AMD cards on the whole have been better for the money, the big advantage of NVidia is the software is much better. See GeForce experience V's craptr.
The big daddy AMD's get hot though, so make sure you have good case ventilation but they are still good value for money.
