It will crash at 1:45 on friday, it was make a strange noise on saturday, then it will blow up on sunday and take your whole PC with it.
hehe what problems will you have? I don't think anyone could answer that, just hope for you its none! Uninstall your old drivers, install the ATi latest drivers and have fun 🙂
AFAIK you can set the video out to either pal or ntsc BTW, ntsc is US, most of the rest of the world is pal. NTSC/Pal only apply to video out/in if you dont use it dont even worry about it.
