I vote g-force, driver wise they update frequently, and support lot of games rather the ATI with poor driver support.
Talk about a false and misleading statement, ATI's current catalyst driver program calls for about 8-10 major driver releases per year, their catalyst program has been on track since it's enception late last year. Not only have they passed NVIDIA in the speed and visual department they have passed them when it comes to customer supprt and driver release and quality.
Your statement may have been true at one time, but that is not the case any longer.
