Recently upgraded from a gtx 560 to an hd 7970 but i've had alot of problems since the start and i can't figure it out. Firstly i've been getting lower fps in some games and I just realised that there had been alot of flickering going on when especially playing games and running programs like Sony Vegas Pro 11. I have been using the same games and programs as i used to but I can't seem to render anything on vegas pro without it flickering extremely and freezing all the time, it used to be fine on my old card
