sorry...caps is my mic key in vent....like i said sapphire cards might be a little different in how they handle drivers...i'm still using 5.3 without issues, but from what i've read it won't work very well on other cards (my buddies 9800 pro is an ATI build and doesn't like it, supposed to be the same chip as mine just uncorked) so it's probably just the different build. ignore what i said, if you have an actual ati card it probably won't work, or work poorly at best
