The only thing they do are rare updates of their legacy drivers but hey now they don't get the money from selling GF2 so why they still update drivers, are they working for free? Do they want to force you to buy new hardware?
Ati on the contrary drops support for 3-4 year old r500. Aren't they force you to buy new chipsets? Think about it who cares more about its bottom line Ati or Nvidia?
