Had 5 nvidia-GPUs since the gforce 2 ti. Had 3 AMD-Gpus since the radeon 9600. Had a Matrox g400 max. People were always complaining. But honestly, i was always satisfied, small flaws, but nothing dramatic unless you picked a broken card. I never experienced such BS from the first day. I´m hardly playing anything at the moment, because I´m waiting for THE DRIVER 2015... And I know multiGPU-setups as i built 2-3 per week in the job i had 2007-2014. they were always bitchy but never that useless.
