Over the past year we have slowly seen new releases of graphics cards come down in price - meaning the new cards we are reviewing are seemingly getting cheaper and cheaper. Is the economy? Is it that gamers just don't want to spend $400 on video cards anymore? Yes and yes, most likely but it is also the windfall involved with releasing your high end parts first and letting the technology trickle down into the cheaper segments. AMD's Radeon HD 4800-series of GPUs were a big success for the company and they are not starting to unleash a wave of new parts based on the RV770 GPU design that use fewer shaders and cost less: enter the Radeon HD 4670.
