You're missing the point. New games were coming out, and my hardware was physically powerful enough to play the games, but since the drivers weren't kept up to date, I couldn't play them. I didn't need to update my graphics card, it was still physically just fine and dandy for the games coming out (although I upgraded my whole computer not long after due to this issue).
Money's not really a huge issue for me at this point my my life and career. I can afford to upgrade my graphics card every few years, but I'm not going to upgrade the damn thing, until I actually need to. If I can still run the games I play, and still play new games I want to play, then why upgrade? Oh right, because AMD wants more money from me...good point. I'll take my money to a company who values their products and shows it by supporting graphic card drivers on cards that are still perfectly fine for running games.
How old are you?
