i don't think so - the drivers are catching up more quickly to newly released cards.They are fooling us, because in 2 years I don't know what to do with an HD 2600 XT gpu. so in the mean time they convince us they are "good" and are working so we buy their cards.
just because the 3d docs aren't available yet doesn't mean that it will be the same for every next generation of cards.
once first 3d documentation will be out it will be much easier for ati to release subsequent 3d docs for next generations of their cards. right now the people preparing the docs have to pass them for IP review, because they don't know for 100% what can they release and what they cannot.
btw i don't the thepart. will your card die or something?in 2 years I don't know what to do with an HD 2600 XT gpu
i still have an x300se card around and it's quite useful for me. what year did it come out, again?
