Is there any way to get vertex shader 2.0 or higher for the intel gma 950 graphics card?

No, I'm sorry but you can increase vertex shader, or shader model in a video card. These 2 things are part of a video card, and cannot be upgraded. You can buy a new video card though. There are a lot of video cards now a days with vertex shader 4, some very cheap (less than 50 dollars). But what do you need the higher vertex shader for? If it's for a program, then there's some files which emulates vertex shader 2 for the program you want. Just follow the instructions. Hope this helps!
