If it is compatible with the 38xx's then it will also be compatible with your 4850, the site has not updated for the new cards as have many manufactueres. I'd recommend zelman, either the vf-900 or 1000. Good quality, quite and until rivatuner works for the fan you still have a manual fan controller, just pair it with a good quality thermal paste and you're golden.
