Hi there,
i have a new Gigabyte GA-MA78GM-UD2H board with AMD X2 processor
For comparison i installed both ubuntu 9.04 and windows7 on it.

under both os'es i installed the latest 9.6 drivers and took it for a test drive on a large lcd display.

under ubuntu dvd playback was not perfect, now and then i saw horizontal displacements of the screen, a little bit sluggish
then i tried a hd clip and this was worse, very choppy
processor went to 100% on one core

next i booted windows7 and both the dvd fragment and the HD clip played very well, very smooth, processor load about 40%

my question am i doing something wrong or is it normal this board runs better under windows?.
