I tried to build a sample application using XNA, but I got an error saying that Pixel Shader 1.1 was required, so I got a used Radeon X300 GPU that supports Pixel Shader.
I tried to build it again, but I got another error saying that "Your current graphics card does not support the XNA HiDef profile" and would not build.
Since that card seems to not be compatible, I guess I need to buy another one. What features should I look for to make sure that it's compatible with XNA?
