Yes, downloaded from that link, and yes, I uninstalled old drivers first...like really..not new to this...one of the few people still posting HWBOT scores for the team regularily..fugger doesn't even do that lately. Anyway, if older drivers or something were istalled, it would show this in the screen i posted up above..with a checkmark if isntalling version is newer, withut check if installing driver is older...

Problem solved by installing driver manually through device manager. Still rendering errors on 4-gpu CrossfireX, single gpu runs fine. This is also noted in teh release notes, tho.
