Where's the point? Why not try to push the frequencies a bit more, instead of going for the easy money with increasing memory? As it's clearly pointed out in the article, with the bandwith being the bottleneck, there's no gain here.
Is there any time when these cards would actually be useful? for certain design apps where you have a lot of graphical data, but it isn't being refreshed that often? Surely there must be some market for them, otherwise why would the companies make them?
You really do well on all these news stories Bungral - much better than places like cpc.
This is marketing.
It's like 10mb or 12 mb compact cameras - does nothing for the performance, actually degrades it because the sensors are too small and there's loads more noise added because of squeezing it all in - 6mb is about the limit for a compact camera. But people buy them - they can say they have a 12mb camera.
People who know nowt will assume a 2gig graphics card is better (wow, 4x better than 512mb).
Maybe it's because ram's cheap at the mo.
Could actually degrade the card if they're using inferior quality ram.
That pretty much covers it.. They will hear the 8800GT is a good card and look at whats on offer.. See one has 4 x the memory of the standard card (8 x that of the 256mb version) and think it must be better.
