One would think that the advent of dual cor CPU's would promt GPU manufacturers to go for DUAL CORE GPU's but this is not the case

nVidia has said that they have no plans to do so because there is no need of DUAl core GPU's.According to a source two nVidia cards on a SLI interface(you don't know what is SLI,I'll post it later)perform better than a dual core Intel or AMD processor.it is an understatement to say that GPU technology are way ahead of CPU technology
by the time DUAL Core become the norm in CPU industru ,nVidia abd ATi will enter into a whole new era .

Unfortunately neither Intel norAMD can match dual GPU speeds and essentially the graphics subsystem is bottlenecked by system architecture.perpahps dual core CPu will reduce loss of speed we have faced.
