Where can you get pixel shader 3.0 and how much would it cost

Pixel Shader is a graphics processing program that runs on the GPU (graphics processing unit) in your video card. There are many versions of PS (Pixel Shader), and I believe at the time of writing the latest version out is 4.1. To get at least PS 3, you will need to get an ATI RADEON x1300-x1900 or a GeForce 6-7 series card, or above. Some of the Intel GMA integrated chipsets support it, but it's emulated and as such will run MUCH more slowly. For a quick chart to this information, please see http://en.wikipedia.org/wiki/Pixel_shaders Search in google shopping as a starting point in searching for a good deal on a video card, but most likely you can get a PS 3 video card for less that $100 US.
