Hi, the best place I can think to look is the driverguide website, however you if you must join, and it's free to join. But some areas, depending upon what you need may require a free or paid membership. I sincerely hope you havent visited this website yet, for this advice will be rendered useless. I did check other sites but could only find drivers for 4000 and up, beginning with driver 8 series. I'm thinking that if all else fails, you may need to use driver 6 series. Good luck!
