The Sapphire HD4650 is a low price GPU based on the 55nm fabricated die that has all the features of the higher priced cards but just not to the extent of the others. Two of the main features of the card is the overclocked 650MHz core and 320 Stream Processors. This is more than enough to support your favorite high def video at a resolution of 2560x1600. And all this can be had for a mere $80.
