I'm not sure I understood the question. You want to know what graphics card you have?You could download CPU-Z. Its a free software that shows you many specs of your computer including what graphics card you have
wat is the model number of my graphics card please tellme??????????
i am not sure what to make of your question. could you provide more information such as your full configuration.
do you have a discreet graphics card in your pc?
is your display connected to your motherboard? if yes, you're using the integrated gpu (inside the core i3 cpu). there are different types of core i3 cpus with different types of igpus. you can download and run programs like techpowerup's gpu-z, piriform's speccy, cpuid's cpu-z and determine what kind of gpu you're running.
