If the market "leader" releases cards at a trickle so they only sell a handful of cards at MSRP, why should the underdog fall on their sword, especially since the at least tried to release a decent number of cards?
Let's also not forget AMD does not manufacture cards at volume, they get them from and OEM to resell. How much do you think AMD was quoted to make a "founder's edition "? Especially when they've already been shafted by selling a fraction of the Nvidia they thought they would.
There was NEVER any chance that AMD was going to keep prices in check, when their 20% of the market were the only cards available for sale. And guess what, despite AMD selling for over MSRP, the sheep are paying even more money for the equivalent Nvida card, when they could get one.
Supply and demand! The market will charge what the market will bear. Especially when the public can't hand over their hard earned cash fast enough!
