I am looking into getting a better video card for rfactor 2 and I would like to get away with just replacing that part of my computer. Can I upgrade to something better for rfactor 2 without changing anything else at this time? What video card would you recommend? I am new to the computer scene and I bought this computer like this minus the power supply (400w before). Thank you. My Specs: AMD Phenom II x2 Gigabyte MA770T-UD3P 4gb (2 x 2GB) ram GeForce 9800 GT 700w power supply.
