Video Card Requirements

I was planning on buying Big Pharma. When I looked to the minimum requirements on Steam, it said I needed a GeForce 600 series or better. I currently have a GT 430 and was interested if I need a GeForce 600 or better to at least start it or my 430 could run it, just not as smooth. I am not a GPU expert myself so I don’t know what the needed specs are that my GPU doesn’t have.
