Memory is only a deciding factor at a price leve. If one of those people see a 512MB card for only $80 and then turn around and see a 256MB going for $500 you know they are going to have a big "wtf" on their face. Price is the biggest deciding factor when buying things, its generally assumed that the higher the price the better it is. Then its, a 512MB $80 must be better than a 128MB $80 card when its often completely opposite.
