Thanks,
I think I've been leaving it on CPU Only as it's the default.

I still have not noticed yet, the Quick sync specific degradation of video quality.

think it's only 'obvious' at very low bit rate...

i did some 'subjective' tests at 4 and couldn't see any noticeable difference, but quick sync was FAST!
