I want to buy a graphic card for my pc but I dont know what model is adapt with my system. please guide me

If you plan on buying a video card, you need to know what type of interface will work with your motherboard. If you are not familiar with the specs, you'll need to open your case, or check the motherboard vendor's website for the specs. Once you find out that information, you can start looking for a compatible adapter.

Thanks. I will try this
