If you have a set budget within which you always keep, then something new comes along approx every 18 months. Eg mid-ranger gen n-1 to mid-range gen n.Just buy a card now. With the tech market no matter when you buy something better will come along within 6 months.
The only time what you said is true is if you always want the very best card, in which case nV will happily release a new Titan (etc) every 6 months
