urrrr I don't think so, perhaps you did,unt do to well in maths at school then, b-cos if ati/nvidia only brought out 1 card per series/gen then ok I could see what your saying but they do not, so, like we see happening here, first we had 7800gtx then 7800gtx extreme then 7800gtx 512 oh and now we have a possible 7800gtx ultra/7900gtx so if you own the original 256mb gtx then it could be a worthy investment, but if you own a 512mb gtx then it could make sense to wait until the next gen, it all depends what end of the spretrum you are and what dates cards are coming out etc, if like most of us you are working with a budget then you don't just willy nilly go out and buy every new gfx card like a sheep, you have to plan and make descisions on what cards to go for and what cards to miss out.
