That can't be normal for my GPU since it has more then enough power to process that with well under the max needed. Me thinks there's a problem somewhere.
If your Radeon 5850 has HDMI out, my guess is that your onboard audio is by Realtek and is confilicting with the Microsoft UAA Bus Driver for High Definition Audio device that installs with the Radeon Catalyst drivers...and running your CPU usage upwards of 100%. I've also seen this behavior on a few systems with Radeon Video cards & Creative sound cards.
Download and run Process Explorer
if you want to find out for sure if this is the issue.
If that's the case, you can try and disable the device in the Device Manager under the System Devices. If that fixes your problem without killing your sound, you're good until the next reboot...note this will kill your HDMI Audio output
. Otherwise, and for what might
be a permanent fix, try installing updated drivers for the HDMI Audio device. The ATI HDMI HD Audio drivers are from Realtek and this has fixed the problem for a lot of folks:
