why god why?

so i'm shopping for a new video card to replace my dead 9700. my system is agp and i don't quite feel like upgrading to a pci express system seeing as how this 2.5 ghz is plenty fast. so i figure i'll get a cheap 6600 agp to hold me over until i update the whole system. anyway, like a kick to the nuts i'm confronted with everyone still selling geforce 2 and 4 mx cards. what is wrong with people?? what possible reason could businesses have for still selling these cards other than to make the lives of game developers miserable??? why haven't all these cards (and the fx5200!) been rounded up and buried in glass bubbles under the ocean?!
