Motherboard : P5QLD-PRO
RAM: 8 GIGS
Old Videocard: NVIDIA GTX260 (Dont have it no more!)
New Videocard: XFX HD6870 ("ZDFC" MODELNR)
OSX: SNOW LEOPARD 10.6.8
Everything worked fine with my GTX260 afterwords i replaced it with my new card the HD6870.
All worked fine til i installed the ATI6xxx PACK.
So if start my system, i can see everything (bootloader -v) till OSX goes in the GUI state and then my monitor just goes black but i can see on that my harddrives loads and it continues to start like always on the GTX.
Thanks Andy for taking your time i hope you have a solution for me i can not even enter my osx now i have a old Leopard system working now but got damn its anoying to go there all the time, the resolution sucks big time.
