Certainly true for this Nvidia generation, it is just a awful position right now, i wish they would go back to tried and true methods, get 3 or 4 cards out, reasonably priced for the performance and make them as good as they can be without so many confusing numbers and models and different memory layouts all over the place combined with rumors and speculation.
Knowing nvidia's history, its entirely possible for them to just screw over the previous series of cards and their owners, i've always liked nvidia cards and if they can give me a good offering for a decent price i would buy from them again but all this stuff is adding a lot of uncertainty and makes me think, what if im gonna get sidelined by new stuff that has more memory for the same price range in a couple of months.
If AMD does well here with the 6000 series cards then this might change stuff up and that would be most welcome!
