I don't have any issues and both my FE's are AMD .. an opteron 170 (dual core)
and an opteron 146 (single core) One is using an 8600GT and the other is using an
8400GS...  both CPU's sit at 1000Mhz even during HD playback.

I did have this issue until I turned off an option that was recommended
(something being synced to opengl)..
