OpenGL 1.3

Hi, I want to add a graphics card to my system because I can’t run True Crime:streets of L.A, right now my system using using the Intel 82865G graphics controller. According to Intel’s website, this graphic controller only supports up to OpenGL 1.3. I have installed the latest driver for this controller. My question is if I buy a graphics card that support Open GL 1.5/higher, can I use it in my system, or do I need to remove the graphic controller first? Please let me know
Thank you!

It depends on your system, but it you should be able to have both controllers, and disable one (from bios if it is an integrated controller).
