That tells us absolutely nothing about the system. What is the make / model of the system? If it's a custom build, what is the make / model of the motherboard? Being it's a low-end pentium 4, most likely it's an AGP based system, and the entire market has moved away from AGP, however, shader model 2.0 is an ancient standard, and most mid-range AGP cards should support it. Even old Radeon 9800's and 6 series Nvidia cards supported it i believe.
