I can not say. But all of my notebooks are using mod drivers from laptopvideo2go.com. All running perfect. Sometimes, there is a buggy one since it is not perfectly tested but overall is good. BTW that drivers are release by Nvidia for specific hardware, laptopvideo2go just unlocked it with modded INF. If you feel the driver is not performed as it should you can always uninstall it from control panel than using to remove driver leftovers from your system.
Have you tried Nvidia site? For the very safe way is stay with Vista, HP will totally support drivers for your notebook.
