No, is normally not like that. Basically AMD is cheaper but requires more power... Alot more! Where NVidia is a bit more expensive but more efficient, in the higher end cards this will actually save you money. Because your almost always going to get a 550w PSU minimum, that will last you up to a 980 Ti (I'm doing it while a larger PSU comes in) though it is a bit nervracking. Where as I think a 550w only takes you up to about a r9 280 which I think is comparable to the 960.
