I have my 3870 updated to Catalyst 8.5 was found with problem on HD watching, especially the HDTV; the CPU utilization for HD was over 50% which shown that no GPU Encoding worked for the HDTV. After installed the hotfix that released on May-21-2008 for Catalyst 8.5, the HD movie and HDTV was OK again, the CPU utilization become lower than 15%. The review by AMD is just too narrow as just 3 to 4 game benchmark is incomplete but I still keep my Catalyst 8.5 since it doesn't show any side effect for overall performance now.
