So I'm deciding to get a new graphics card I have my eye on either the GTX 970 or R9 290x/390x I read on a different thread that Nvidia drivers are causing systems to crash. I have never used Nvidia before but it seems to be a lot more energy efficient compared to Amd currently I'm running a HD 6990 which is a power guzzler so any new card will save me on electric but I am worried I am going to have regular problems with the Nvidia drivers. I am running 3 monitors 2 DVI monitors and 1 VGA I know I probably should invest in a new monitor and also I know I will not be able to run the VGA on AMD latest cards without a active DP to VGA adapter. But first the GPU then will think about that. Any help and advice would be great.
