IMHO, this is actually the best time for ATi to win marketshare with nVidia retreating a bit from competition -since they have nothing for competition against Evergreen cards, so decreasing the price as yield improve would be very reasonable, margin would still be healthy while stealing lots and lots of marketshare before Fermi and its lower end derivatives arrive.

HD 5870X2 4 GB @499 US$
