My friend has a 9800 pro and plays RVS. He sometimes crashes to desktop and gets those errors with RVS that you can submit, but I dont know if that would be reloated to video card or not. I have a supported video card(9700 pro) and I get that too sometimes. My guess is that it will work.
I have a 9800pro and the game works fine, infact rvs came with my grahpics card. Only problem i have is the anti aliasing dies and the jaggy lines come back when i use the nightvision or when i get shot. This is driver releated and has done this since i upgraded from 3.8 to 4.10 version of the catalyst drivers.
