I'm really starting to hate ATI's arrogance where drivers are concerned. Can't these fu**ing guys ever just put out a driver that installs... with no other bulls**t issues? I just spent two hours loading and reloading different drivers to find a working one ...to no avail on a brand "spanking" new Sapphire HD 4850 X2 /2GB. This, for a friend who insisted on having it...despite my warning. ATI counts Sapphire as a business ally in the X2 venture and vice versa...so the chat about it not being supported by ATI is bunk. The darn computer was running solid since I built it a few months ago...now after removing the GTX card, drivers and registry entries....and loading ATI's latest catalyst 9.2 and trying everything back to 8.11 with the new card...I'm getting error code 43 with the second GPU being disabled and an incompatibility message in the taskbar. Damn it ATI....build a decent driver for once.
