Every time over the years, that we have had debates about if a card has enough ram, the side saying it doesn't, have been proven correct. Same for features like Vulcan an DX version. Certainly, there is the point that for much of our crowd i.e. forum dwellers, that by the time it matters it is irrelevant. But then again, none of these guys are buying those cards. Easy to recommend a card that is going to age like warm milk, to someone else, when you won't be the one stuck with it. Or buying it for way too much money for 2yrs of complete insanity in the market.
The lower the settings talking point is fine. That is, when all other things being equal, the buyer could not have bought a different card where that isn't necessary. Textures have become a great visual without big performance penalty. Being forced to lower those on a card otherwise plenty powerful enough to run the game, is a major bummer. Especially when the guy that bought a card with more ram for the same or less money, doesn't have to do it.
